Win9x segfaults with Voodoo Recompiler

Post by SA1988 »

When the voodoo recompiler is enabled and I try to do some Direct3D tests like dxdiag, it segfaults with voodoo_x86_data() being at fault.
Note: I'm using the Voodoo1 drivers from 1999 for win9x.
Drivers: http://www.falconfly.de/voodoo1.htm 01 May 1999 ones.

It's the emulator that segfaults when DXDiag is run on Windows 95 with the Voodoo recompiler enabled and it seems the 1999 Voodoo drivers.

Doesn't segfault here on Win95 and Win98SE with DX7's dxdiag and May 1999 drivers, and 2mb / 4mb frame buffers.

What are your compiling flags? Mine are the standard makefile, plus -flto.

- leilei: CFLAGS = -O3 -march=core2 -mtune=core2 -fbranch-probabilities -fvpt -funroll-loops -fpeel-loops -ftracer -fomit-frame-pointer -ffast-math -msse -msse2 -msse3 -mssse3 -mfpmath=sse -mstackrealign -DRELEASE_BUILD .

But I also have another user who says he did not have the problem with the same binary.

Can you provide a register dump and a disassembly of voodoo_x86_data from GDB at the time of the crash please?

Sorry to ask, but do I have to generate it with "bt" in gdb?
Edit: nvm, figured out: here's the full log.

Post by SarahWalker »

Do you have Data Execution Prevention turned on in Windows? The Voodoo recompiler should be handling that, but it's possible I made a mistake somewhere.

Of course, you disabled the following:

Code: Select all

                if (voodoo->use_recompiler)
                {
                        voodoo_draw(state, params, x, real_y);
                }
                else
Edit: SA1988 says he got the Voodoo recompiler to work by setting DEP to Only essential Windows programs and services. This means the Voodoo recompiler currently doesn't with DEP enabled.
