Unsure, but with gdb from the commit prior to the bisection:
(64-bit chroot) catbus ~ # gdb -q t
Reading symbols from t...
(gdb) start
Temporary breakpoint 1 at 0x7b8: file t.c, line 4.
Starting program: /root/t
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
Temporary breakpoint 1, main () at t.c:4
4 printf("hello world\n");
(gdb) info sharedlibrary
From To Syms Read Shared Object Library
0xfff80001000010a0 0xfff8000100021f80 Yes (*) /lib64/ld-linux.so.2
0xfff800010032ae00 0xfff800010045ac80 Yes (*) /lib64/libc.so.6
(*): Shared library is missing debugging information.
