--- Comment #6 from Martin Liška <marxin at gcc dot gnu.org> ---
Sorry for not providing a test-case, here we go:
$ cat test.c
#include <stdio.h>
void foo (int argc, char **argv)
{
fprintf (stderr, "%s%s\n", argv[0], argv[1]);
}
void bar (int argc, char **argv)
{
foo (argc, argv);
}
int main(int argc, char **argv)
{
bar (argc, argv);
}
$ gcc -Og test.c -g
$ gdb ./a.out
(gdb) b foo
Breakpoint 1 at 0x401112: file test.c, line 4.
(gdb) r
Starting program: /home/marxin/BIG/Programming/linux/tools/perf/a.out
