hipe segmentation fault

[Serge Aleynikov]

Ops...  Sorry, this test case was taken from Rickard Green's post on 
profiling P11B smp scheduling support.  I wanted to run it on multi-cpu 
host, and installed R10B-10 and P11B releases with and without hipe.

I don't think this problem is related to some memory corruption.  This 
is what I tried to do in order to diagnose the problem:

I recompiled erts with gcc's "-g -O0" options, and then:

$ ulimit -c unlimited
$ erl -emu_args
Executing: /usr/local/lib/erlang/erts-5.4.13/bin/beam 
/usr/local/lib/erlang/erts-5.4.13/bin/beam -- -root 
/usr/local/lib/erlang -progname erl -- -home /home/serge

Erlang (BEAM) emulator version 5.4.13 [source] [hipe] [threads:0]

Looking at hipe_x86_glue.S:42:

x86_call_to_native:
     ENTER_FROM_C
     /* get argument registers */
     LOAD_ARG_REGS
     /* call the target */
     NSP_CALL(*P_NCALLEE(P))  <-- Failing here

I'm not sure what this call does, but maybe Mikael can give a clue.

Regards,

Serge
