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

[PeteVine]

A simpler way to reproduce would probably be to wrap the regular,
installed rustc that way and try running some compilations using cargo.
That should be enough to elicit the same problem.

Title:
  qemu-i386-user on 32-bit Linux: uncaught target signal 11

Status in QEMU:
  New

Bug description:
  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.
