Release candidate for Blocek 1.74 (Developers)

posted by Laaca Homepage, Czech republic, 19.07.2023, 18:47

It crashes between 2/3 and 3/3?
Interresting.
In this section Blocek reads all the configuration settings. There is nothing special what could crash the virtual machine.
But it also does two other things:
1) Disables default FPC/DJGPP handling of CTRL-C and CTRL-Break (the normal behaviour is exception which kicks off the program as you saw in the 1.74 vanilla version)
2) Makes an experiment with calling the SSE instruction.
For this purpose it redirects exception handlers for signals SIG_ILL and SIG_GPF. Then calls some SSE instruction ({movaps xmm1,xmm2}) and then reverts the SIG_ILL and SIG_GPF to original state.

I don't know whether is possible to be a bug in DOSEMU in implementation of this. On real SSE hardware is no problem. On real hardware without SSE (pentium 1) also no problem.
DOSBOX-X (at least the version which use I) also OK. But maybe other emulated environments...

I am not home today and sure about tomorrow so I can't assist you right now.
But do you some possibility to change the setting of the SSE instruction support in your virtualization?
