[Qemu-devel] QEMU 0.10.0 crash on Win32

[Robert Riebisch]

Hi!

Firstly, thanks to all contributors for the new release! :-)

While QEMU 0.10.0 built using MinGW GCC 3.4.5 runs fine with KQEMU
enabled, a build made with GCC 4.3.0 (alpha) crashes on Win32, when
booting Avira's Rescue System ISO.

***
Program received signal SIGSEGV, Segmentation fault.
kqemu_cpu_exec (env=0x3d9e2ff8)

Host CPU: Pentium M (Banias)
Host OS: Windows 2000 Pro SP4
KQEMU version: 1.4.0pre1

Any idea?

Could you try TDM's build of GCC 4.3.3 if it works better?

Were you using the 1.3 or the 1.4 kqemu?

Quoting myself: "KQEMU version: 1.4.0pre1"

Recent QEMU 0.9.1 SVN or 0.10.0 won't work with KQEMU 1.3. It will
display "Version mismatch between kqemu module and qemu" instead.

Oops. Sorry. I didn't look back far enough :).

I'll give it try myself and see if I can reproduce. I'm using tdragon as 
well. I haven't had an issue with arm, but I haven't tried x86 either.

Doug.

I switched back to GCC 3.4.5, but the problem was still there. Next step
was to also switch back from binutils-2.19.1-mingw32-bin.tar.gz to
binutils-2.17.50-20060824-1.tar.gz and this fixed it!

A combo of gcc-part-XXX-4.3.0-20080502-2-mingw32-alpha-bin.tar.gz +
binutils-2.17.50-20060824-1.tar.gz does *NOT* crash.

Trying binutils-2.18.50-20080109-2.tar.gz +
binutils-2.18.50-20080109-2.tar.gz: Crash!

In binutils-2.18.50.0.1/opcodes/ChangeLog I find: "Use M on fxsave and
fxrstor." I don't know, if this is the cause of the trouble.

Command line to reproduce: qemu.exe -m 512 -cdrom
rescue_system-common-en.iso -boot d -localtime

rescue_system-common-en.iso is "Avira AntiVir Rescue System" version
20090306172230 from <http://www.avira.de/en/support/support_downloads.html>.
