- * right after entering main(). Another is right before we finish, before
- * we start executing any process termination code.
- *
- * Another problem we have to guard against, at least for the test
- * suite, is that we need to ensure that the line that causes the
- * watchpoint to be hit is still the current line when gdb notices
- * the hit. Depending upon the specific code generated by the compiler,
- * the instruction after the one that triggers the hit may be part of
