[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.

My recollection is fuzzy but it would probably amount to something like
this on any platform currently:

- download rust-1.10 beta source https://static.rust-lang.org/dist
/rustc-beta-src.tar.gz

- download this stage0 snapshot
https://www.dropbox.com/s/01ywl9mwwo6xojw/rust-stage0-2016-04-18-b324fa7
-linux-armv7.tar.xz?dl=0

- unpack the stage0 rustc binary to ~/somewhere/bin, renaming it to
rustc.bin, and create a wrapper script named rustc in that directory
containing:

`/usr/bin/qemu-arm ~/somewhere/rustc.bin "$@"`

In the rustc source directory, start the rust bootstrap process (with LLVM 3.7 or higher installed) issuing the following command:
`./configure --enable-optimize --enable-local-rust --local-rust-root=~/somewhere --llvm-root=/usr`

Followed by `make`.

At the time of the original report, QEMU wasn't able to complete all
crates' build commands naturally. (the stamp file had to be created
manually to continue)

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.

Looking through old bug tickets... can you still reproduce this issue
with the latest version of QEMU?
