actually, in gdb, I find that the variable is not corrupted:
(gdb) bt
#0 0x000000000089dc94 in __message_passing_MOD_mp_stop ()
#1 0x000000000050ed2e in __cp_log_handling_MOD_cp_add_default_logger ()
#2 0x000000000059a897 in __f77_interface_MOD_init_cp2k ()
#3 0x0000000000d49638 in MAIN__ ()
#4 0x0000000000e8786c in main (argc=2, argv=0x7fff1e9b6768) at
/data/vondele/gcc_trunk/gcc/libgfortran/fmain.c:22
(gdb) up
#1 0x000000000050ed2e in __cp_log_handling_MOD_cp_add_default_logger ()
(gdb) print __cp_log_handling_MOD_stack_pointer
$1 = 0
(the variable should be 0), but it looks like the assembly might be wrong:
g.s:
.LCFI15:
call mcount
cmpl $9, __cp_log_handling_MOD_stack_pointer(%rip)
movq %rdi, %rbx
jle .L21
movl $108, %edx
movl $.LC8, %esi
movl $.LC9, %edi
call __message_passing_MOD_mp_stop
b.s:
.LCFI15:
cmpl $9, __cp_log_handling_MOD_stack_pointer(%rip)
call mcount
movq %rdi, %rbx
jle .L21
movl $108, %edx
movl $.LC8, %esi
movl $.LC9, %edi
call __message_passing_MOD_mp_stop
