Default Bug#535755: /usr/bin/gcov-4.3: gcov produces wrong answers when given more than one source file

Package: gcc-4.3

Severity: important
File: /usr/bin/gcov-4.3

The gcov man page reports that one can give gcov multiple source files
at one invocation. This does not work:

gcov -o BUILD-Linux-i686--coverage ../src/*.c

reports that most source files contain 'No executable lines'.

for i in ../src/*.c; do gcov -o BUILD-Linux-i686--coverage $i; done

produced sensible answers.

This is probably a problem for upstream, but an immediate fix would be
to alter the man page to warn users that they can give only one source
file at a time.

please could you recheck with gcc-4.4 (unstable), gcc-4.5 (experimental),
gcc-snapshot (unstable)?
