[Qemu-devel] [Bug 1529226] [NEW] qemu-i386-user on 32-bit Linux: uncaught target signal 11

[PeteVine]

Public bug reported:

Even though the command I'm trying to run (a wrapper script for
qemu-i386-user running rustc, the rust compiler)  produces the expected
compiled output, the build process is interrupted:

qemu: uncaught target signal 11 (Segmentation fault) - core dumped
i686-unknown-linux-gnu/stage0/bin/rustc: line 1:  7474 Segmentation fault      
/usr/local/bin/qemu-i386 -cpu qemu32 /home/petevine/stage0/rustc.bin -C 
target-cpu=pentium2 -L 
/home/petevine/unpacked/rust-master/i686-unknown-linux-gnu/stage0/lib/rustlib/i686-unknown-linux-gnu/lib/
 "$@"
make: *** 
[i686-unknown-linux-gnu/stage0/lib/rustlib/i686-unknown-linux-gnu/lib/stamp.rustc_back]
 Error 139

The stamp file is not being created so this could be about forking bash
after finishing the wrapper script.

Qemu was compiled from the latest git source.
