I wished many times that above worked, but it doesn't: 'finish'
appears to interrupt flow of script, and subsequent commands are
never executed:

  cat t.c
  int foo() { return 42; }
  int main() { return foo(); }

  gcc -g t.c

  (gdb) b foo
  Breakpoint 1 at 0x400310: file t.c, line 1.
  (gdb) commands 1
  >finish
  >print/a $pc
  >continue
  >end
  (gdb) r

  Breakpoint 1, foo () at t.c:1
  1       int foo() { return 42; }
  0x0000000000400325 in main () at t.c:2
  2       int main() { return foo(); }
  Value returned is $1 = 42

# Neither 'print/a $pc' nor 'continue' executed :(

  (gdb) q



Is this a bug?
