GDB does, why not?  The prologue skipping processes already decoded debug
info, no matter if it is DWARF or STABS.

gcc -Wall
Breakpoint 1 at 0x400478
gcc -gstabs
Temporary breakpoint 1 at 0x40047c: file 24.c, line 3.
(gdb) p/x $pc
$1 = 0x40047c
gcc -gdwarf-3
Temporary breakpoint 1 at 0x40047c: file 24.c, line 3.

Sure STABS is discouraged.


Regards,
Jan
