I am trying to proceed backward. I have reached the following point:
Breakpoint 8, gfc_parse_file () at ../../gcc-4.3-work/gcc/fortran/parse.c:3460
3460 {
(gdb) s
gfc_parse_file () at ../../gcc-4.3-work/gcc/fortran/parse.c:3466
3466 gfc_start_source_files ();
(gdb) print gfc_current_ns->common_root->n.common->head->common_next
Cannot access memory at address 0x8
(gdb) print gfc_current_ns->common_root

(gdb) print gfc_current_ns
$13 = (gfc_namespace *) 0x0
(gdb) s

348 {
(gdb) s

355 report_file_change (gfc_current_locus.lb);
(gdb) print gfc_current_locus.lb
$14 = (gfc_linebuf *) 0x40d06700
(gdb) print debug_hooks->start_end_main_source_file
$15 = 0
(gdb) print gfc_source_file
$16 = 0xbfffeec7 "1234567.f90"
(gdb) print file_changes_cur
$17 = 0
(gdb) print *debug_hooks->start_source_file
$18 = {void (unsigned int, const char *)} 0x339b70 <debug_nothing_int_charstar>
The "warning: Got an error handling event: "Cannot access memory at address
0x7" look bad, but I do not see where they come from.
