HX 2.12 vs HT Editor 2.0.8 (DOSX)

HT Editor crashes with "exception caused by access to memory address..." when I try to open, e.g., C:\COMMAND.COM in MS-DOS 6.22. Some other files work fine. Anybody else?

EDIT: URL added :-D

I have MS-DOS 6.22, so I can test this if you want. However, are you saying it messes up when you view COMMAND.COM or just running HT via COMMAND.COM?

Maybe it's a path bug. Or try running 4DOS (or FreeCOM) as shell and see if the problem disappears.

Please do so! :-) I fear Japheth seems not to be interested in this issue.

It crashes when loading COMMAND.COM (or some other binary files) for viewing.

> Maybe it's a path bug.

I don't think so.

Yes, I'm quite interested, but since it's apparently a problem for MS-DOS 6.22 only I think it's negligible :) .

Sorry to prove you wrong, Japheth.

But it was you who gave this information:

:confused:

what's also confusing is that the errors in the post above are exceptions C0000092h, which is - according to Win32 docs - a floating point stack exception, while the exception in the original post is a page error (exc 0Eh).

You didn't notice "e.g." and "some other", did you? :-D I just gave C:\COMMAND.COM as an example for a default DOS installation.

Of course, HT also crashes on other files. Mostly "binary".

Sorry for being ~~"inexact"~~ ambiguous.

OK, here's a new error message:

dkrnl32: exception C0000005, flags=0 occured at BF:4E0090 ax=3246E0 bx=1 cx=0 dx=90 20 2007 si=0 di=1 bp=324BBD sp=3246E0 exception caused by access to memory address 24148903 ip = Module 'ht.exe'+E0090 dkrnl32: fatal exit!

Done in Bochs 2.3 with MS-DOS 6.22 after getting exception C0000092.

It might be related to the MinGW development environment, because sometimes I get similar errors with my own Mutt/Win32 project. I'll try to make HT build with Visual C++ 2005 Express and post results here.

Sorry, I give up on cstream.cc now. It's a rather complicated task for a novice. :crying:

Okay, first of all, HT 2.0.8 is precompiled as a Win32 binary only (and src, too), but I was unable to compile via DJGPP (maybe b/c no flex or bison installed?? I dunno). Anyways, it needed MSVCRT.DLL, so I didn't really have that on my old cpu (only old old MSVCRT20.DLL from Win95, heh, didn't work even when renamed, oh well).

Not that it compiled for me, but it supposedly used to compile with DJGPP (see 0.7.5 prebuilt binary), so at worst, just use that for now. ;-)

What does this program do exactly besides fancy .EXE multi-header view, hex editing, disassembling, etc.? ("analyze" ... show potential regs??). It doesn't do (much else) that BIEW doesn't, does it?

I guess I could later test HT-2.0.8 + HXRT on my Win XP cpu w/ its own newer MSVCRT (with its included files for WinME bootdisk or maybe even DOSBox 0.71), but that probably won't work either. :-|

DJGPP port is broken. That's why I called this thread "HX vs HT Editor". ;-)

Copying MSVCRT.DLL should be easy.

The DOS port has been officially abandoned since 0.7.5. (However, I've been told it doesn't need flex or bison, but I still haven't tried compiling again yet. Supposedly, the author just opened RHIDE, added all files, and then compiled.)

Actually, I couldn't get it to compile in Damn Small Linux (0.33) either (GCC/G++ 3.2.3), so I dunno really. It mostly compiled but bombed out on that blasted "analyser". :-|

EDIT: The author uses Cygwin to compile.

I did that today (WinXP P4 cpu), copied MSVCRT.DLL (343k) and put \BIN\*.* from HXRT.ZIP and HXGUI.ZIP (just in case), then tried running HT 2.0.8 from within DOSBox 0.71. It kinda sorta loaded up okay (except weird extended ASCII chars), but always bugged out "wrong magic/format" when opening anything. And it did crash a few times (e.g. "exception C0000005", IIRC). And it didn't work in Wine 0.9.22 (Damn Small Linux 0.33) either.

BIEW is better for normal use. I still don't understand the huge advantage / usefulness of the "analyser". :confused:

That's exactly, what Sebastian Biallas told me. :-P

Could this be the problem, Japheth? see Re: [Mingw-users] The application failed to initialize properly(0xc0000005)

With current HXRTD and HT 2.0.9 I get the following error message, when selecting mode "some statictext".

dkrnl32: exception C0000005, flags=0 occured at BF:36FAE3 ax=3248CC bx=681360 cx=0 dx=2 si=324900 di=D002FDF9 bp=15014DC sp=3248CC exception caused by access to memory address D03AA735 ip = Module 'msvcrt.dll'+28AE3 dkrnl32: fatal exit!

then don't do that!

it's a bug in HT. :)

I read in the HT help that DGJPP is supported as target. Where is the binary?

I don't think so (unless something changed from 2.0.8 to 2.0.9, highly unlikely). The author told me via e-mail that DJGPP wasn't supported since 0.7.5 (which does have a binary available).

It doesn't expect CRT function localtime() to fail, which is a bit careless.

OTOH, localtime() failed because not all file times are available in DOS (or FAT32?) and hx didn't clear those in Win32 structure BY_HANDLE_FILE_INFORMATION.
