Description Andy Theuninck 2012-02-03 21:39:05 UTC 
Description of problem:
My erl binary crashes instantly with an "Illegal instruction" error.

Version-Release number of selected component (if applicable):
Erlang (ASYNC_THREADS) (BEAM) emulator version 5.8.4, provided by package erlang-erts-R14B-03.3.el6.i686

How reproducible:
Always

Steps to Reproduce:
1. yum install erlang-erts-R14B-03.3.el6.i686
2. erl
  
Actual results:
$ erl
Illegal instruction

Expected results:
Erlang emulator shell prompt

Additional info:
Very amateur gdb investigation (the debuginfo-install command suggested fails to find anything):
(gdb) run
Starting program: /usr/lib/erlang/erts-5.8.4/bin/erlexec 
process 12368 is executing new program: /usr/lib/erlang/erts-5.8.4/bin/beam
[Thread debugging using libthread_db enabled]

Program received signal SIGILL, Illegal instruction.
0x080bf532 in schedule ()
Missing separate debuginfos, use: debuginfo-install erlang-erts-R14B-03.3.el6.i686
(gdb) backtrace
#0  0x080bf532 in schedule ()
#1  0x0812f7e9 in process_main ()
#2  0x080815cb in erl_start ()

It seems to be fixed in R14B04. I've just tested in a Qemu/KVM.
