It's not the right fix, though, because from a console the temporary breakpoint
now gets reported when execution stops.
Currently:
(gdb) tbreak main
Breakpoint 1 at 0x8048687: file myprog.c, line 95.
(gdb) run
Starting program: /home/nickrob/myprog
main (argc=1, argv=0xbfcacf74) at myprog.c:95
95 main (int argc, char **argv) {
(gdb)
After your change:
(gdb) tbreak main
Breakpoint 1 at 0x8048687: file myprog.c, line 95.
(gdb) run
Starting program: /home/nickrob/myprog
Breakpoint 1, main (argc=1, argv=0xbf844314) at myprog.c:95
95 main (int argc, char **argv) {
(gdb)
