setjmp/longjmp in Symbian OS

Hi!
I try to use setjmp/longjmp instructions, but application fails with
KERN-EXEC 3. Code is very simple:
int Main()
{
jmp_buf jump_buffer;
if ( setjmp( jump_buffer ) == 0 )
{
longjmp( jump_buffer, 1 );
}
return 0;
}

Anybody used setjmp/longjmp (in Symbian)? Share experience, please.
Thanks.

The functions setjmp and longjmp are for C-style stack unwinding and
are discouraged in C++ because they are incompatible with exception
handling (TC++PL, 16.1.2). I'd suggest you post this either in
comp.lang.c or in a newsgroup related to Symbian.

Cheers! --M
