Bug#365123: gcc-4.0: gcov opens files with O_RDWR

["Ph. Marek" <philipp.marek@bmlv.gv.at>]

X-Reportbug-Version: 3.20
X-Debbugs-Cc: philipp.marek@bmlv.gv.at
Package: gcc-4.0
Version: 4.0.3-2
Severity: important

gcov opens it's data files *.gcda and *.gcno with O_RDWR.
This fails if these files were created by another user, and the current user 
only has read access to those files.

I believe that to be a major bug - opening files O_RDWR when only read access 
is needed.
(At least, in strace I only see read()s).


Regards,

Phil
