Bug#435907: gcc-4.1: Empty ; causes programs built with profiling to hang

["Michael Casadevall,,," <sonicmctails@gmail.com>]

Package: gcc-4.1
Version: 4.1.2-13
Severity: important

cause an endless loop. I attempted to debug with gdb, but that crashed 
to. I've included a test file that reproduces the problem. Also 
reproduced with gcc-4.2
