--- Comment #40 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
I am correct to assume that there is no workable debugger capable of debugging
gcc on our AIX boxes?
power8-aix:~/bisect-succeeds/gcc$ gdb cc1
GNU gdb (GDB) 7.8.2

(gdb) break main
Breakpoint 5 at 0x10000394: file _start_ , line 37.
(gdb) run
Starting program: /home/aldyh/bisect-succeeds/gcc/cc1
Breakpoint 5, main (argc=<error reading variable>,
argv=<error reading variable>) at _start_ :37
37 _start_ : A file or directory in the path name does not exist..
(gdb) list
32 in _start_
(gdb) next
35 in _start_
(gdb) next

(gdb)
I also tried dbx, which doesn't seem very willing to even load cc1.
