Just it will not work on reload of the executable changed underneath where PCs
change as EXPLICIT_PC needs to be in charge.
But it already does not work now for `run':
echo 'main(){l:;}'|gcc -g -x c -;../gdb -nx ./a.out
[...]
(gdb) start
[...]
(gdb) b l
[...]
(gdb) cont
Continuing.
Program exited with code 070.
(gdb) run
Starting program: .../a.out
Error in re-setting breakpoint 2: Function "l" not defined.
symtab_and_line->symtab is too general, there should be symtab_and_line->block.
Regards,
Jan
