Summary: cygwin not working inside 64-bit guest
Initial Comment:
I installed cygwin on Windows XP x64 inside kvm-59 and it crashes randomly. The
easiest way to reproduce it is by simply starting and quitting a few bash
shells:
-------------------------------
C:\cygwin\bin>Cygwin.bat
C:\cygwin\bin>bash
bash-3.2$ bash
bash-3.2$ bash
bash-3.2$ exit
exit
10551 [main] bash 1488 sig_send: wait for sig_complete event failed, signal
-34, rc -1, Win32 error 6
Segmentation fault
bash-3.2$ exit
exit
87 [main] bash 1592 sig_send: wait for sig_complete event failed, signal
-34, rc -1, Win32 error 6
Segmentation fault
bash-3.2$ exit
exit
C:\cygwin\bin>
-------------------------------
But it also happens with other programs so it seems to be something related to
their weird fork implementation.
With kvm disabled (with kvm-56 as it won't boot anymore with 59), cygwin works
fine.
Host is a Core 2 Duo with slackware 11 and kernel 2.6.21.1. Running with:
qemu-system-x86_64 -hda wintest.img -smp 1 -localtime -net nic,model=rtl8139
-net tap,ifname=tap0,script=no -m 512
