I've managed to enter this as a bug at http://gcc.gnu.org/bugzilla only to
find that it has already been reported as bug 7970 (Arc profiling doesn't
work reliably on global destructors) in Sept 2002 on gcc 3.2.1
So, the only way I can think to get around this is to reprocess the gcov
output files.
Is there anyone with some good ideas?
