qemu-system-ppc 5.0 rc1 crashing on Windows

[Howard Spoelstra]

Hi,

I just compiled qemu-system-ppc for Windows, using native msys2 on Windows 10 64 bit and the 64 bit mingw cross compiler on Fedora 31. Both create executables that crash:

qemu-system-ppc.exe -L pc-bios -boot c -m 512 -M mac99,via=pmu -h
da C:\Mac-disks\9.2.img
Exception code=0xc0000005 flags=0x0 at 0x00007FFB2A602078. Access violation - attempting to write data at address 0x00000000034C76EC

I bisected this down to:

d2cd29e30736afd4a1e8cac3cf4da360bbc65978 is the first bad commit

    configure: Do not force pie=no for non-x86
   
    PIE is supported on many other hosts besides x86.
   
    The default for non-x86 is now the same as x86: pie is used
    if supported, and may be forced via --enable/--disable-pie.
   
    The original commit (40d6444e91c) said:
   
      "Non-x86 are not changed, as they require TCG changes"
   
    but I think that's wrong -- there's nothing about PIE that
    affects TCG one way or another.
   
    Tested on aarch64 (bionic) and ppc64le (centos 7) hosts.

Please note that I tried again after applying patch https://patchwork.ozlabs.org/patch/1265368/ However, this has not solved my issue.

Best,
