(I am reposting this as my first post seems to have fallen through the
cracks.)
I am building the official Qemu 1.7.0 release from source natively under
MinGW for myself. I execute the i386 target. Qemu starts fine, but it
crashes when I try to partition a 2G hard disk under an MS-DOS 6.22 guest.
Details of the build and reproducing the crash are below.
The problem also occurs for me with the 1.6.2 release. The problem does not
occur with these binaries from other people:
Eric Lassauge's Qemu-1.6.0-windows.zip
Prashant Satish's qemu-1.6.0-win32-sdl.tar.lzma
Stefan Weil's qemu-w32-setup-20131128, qemu-w32-setup-20140118.exe
The problem does not occur when I add the --enable-debug flag to configure!
Whatever optimisation is removed as a result seems to avoid the crash.
How can I troubleshoot what the problem is? What should I change about my
build to solve the problem?
Host: Windows 7 64-bit
Build environment: (32-bit)
MinGW fresh install including:
mingw32-gettext bin 0.18.3.1-1
mingw32-gettext dev 0.18.3.1-1
mingw32-gettext dll 0.18.3.1-1
mingw32-libintl dll 0.18.3.1-1
mingw32-libz dev 1.2.8-1
mingw32-libz dll 1.2.8-1
MSYS shell fresh install
Glib libraries and dependencies:
glib_2.34.3-1_win32
glib-dev_2.34.3-1_win32
pkg-config_0.28-1_win32
pkg-config-dev_0.28-1_win32
SDL-devel-1.2.15-mingw32
Qemu 1.7.0 source is in /mingw/build/qemu-1.7.0
Build process: (out-of-tree build)
using MSYS shell, in /mingw/build/qemu-1.7.0-obj directory:
../qemu-1.7.0/configure --python=C:/Python27/python --prefix=/mingw/build/qemu-1.7.0-bin
--target-list="i386-softmmu" --disable-coroutine-pool
make
make install
To reproduce crash:
have a 1.44 floppy image of MS-DOS 6.22 boot disk
place the disk image with name dos.img in /mingw/build/qemu-test directory
using MSYS shell, in /mingw/build/qemu-test directory:
../qemu-1.7.0-bin/qemu-img create -f qcow2 test.img 2G
../qemu-1.7.0-bin/qemu-system-i386 -fda dos.img -hda test.img -boot a
once DOS boots up, type fdisk and try to create a single partition using all
available space
Qemu crashes
