i686 GNU/Linux, seg-fault on executing rust tool-chain binaries

[rajputrajat]

When I am running following,
$rustc
I see Segmentation fault. The same happens with other binaries as well.

This is the output of uname -a from this linux box:
Linux suse-13-2-rajput 3.9.2-51 #1 SMP PREEMPT Mon Jan 1 00:00:00 UTC 2007 i686 i686 i386 GNU/Linux

I have added output of /proc/cpuinfo as cpuinfo.txt
cpuinfo.txt

The binaries execute fine, if I run with strace or valgrind.
This is how, I was able to install rustup on this system, as rustup-init was also seg-faulting.

Please let me know, what I can do more to investigate.

Can you run under gdb and try to obtain a backtrace? Can you say which rustup-init you used (or which rustc)?

gdb is not showing any stack.
following is output from cross-compiled one. same was happening with tool-chain binaries.

same is true with gnu variant of toolchain. also with i686.

rust-lang version is 1.48.0
rustup is 1.23.1
not sure about rustup-init, but it was the one for i686.

Although, binary name says simple_print, but it wasn't.
simple print does actually work fine here.
This one is with rand crate usage.

We support i686-unknown-linux-gnu and test it as a host. That means that this can't be segfaulting just on the binaries. So as there isn't an obvious reason why this segfaults, so it must be under special conditions. Closing as a no-repro segfault is not something we can investigate.

Also the box supports 64-bit so I don't even know why it is on 32-bit.
