           Summary: gcov freezes when using --all-blocks (-a) flag.
           Product: gcc
           Version: 4.3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: lieutenantfeist@hotmail.de


lcov stopped processing files and was stuck on particular ones. The problem was
eventually narrowed down to the gcov call which, when enabling error and std
output, showed that it got stuck while trying to create a
'#path#to#current#header.h.gcov' file. Making sure that gcov is not called with
the -a (or --all-blocks) flag enabled, allowed gcov to finish successfully.
This does not apply to all .gcda files being analyzed, just some files which
aren't drastically different from others which get processed fine when using
the -a option.
