CoreDump STLinux

Hi all,

First of all sorry to send an email to linuxsh-dev list directly, I
doing it because my attempt to use linux-sh@m17n.org fail (its site is
down).

My problem:
I trying to analyse a core-dump of "Hello-world" like app that is
running on SH4-STLinux, but it fails.

gdb gives me :

(gdb) bt full
#0 0x297382d4 in raise () from
/opt/7109/STM/STLinux-2.2/devkit/sh4/bin/../target/lib/libc.so.6
No symbol table info available.
#1 0x29739dd6 in abort () from
/opt/7109/STM/STLinux-2.2/devkit/sh4/bin/../target/lib/libc.so.6
No symbol table info available.
Cannot access memory at address 0x7b916ff8

My program code:

#include <stdlib.h>

extern void m1();

static int count = 0;

void m3(){
if (count++ > 2)
abort();
m1();
}

void m2(){
m3();
}

void m1 (){
m2();
}

int
main (int argc, char* argv[]) {
m1();
return 0;
}

I compiled it with /opt/STM/STLinux-2.2/devkit/sh4/bin/sh4-linux-g++
-g -o mysand sandbox.cpp

I've tried -fstack-protector-all option without success too.

Before running it on STLinux I'm running: ulimited -c unlimited.

Do you have any idea why the stack of my core-dump is broken ?

Thanks in advance,
Rafael Torres
