I'm trying to use gcov with gcc 4.1.1 as installed in Fedora Core 6 x86_64. This works fine: gcc --coverage -o hello hello.c This does not: gcc --coverage -o hello.o -c hello.c gcc --coverage -o hello hello.o Both work as expected with Apple's gcc 4.0.4 (with explicit -fprofile-arcs -ftest-coverage) and FSF gcc 4.1.2 on powerpc or gcc trunk on x86_64. I thought I'd heard of this on gcc@xxxxxxxxxxx, but I've looked in Bugzilla and cannot find it. If this is known I'd appreciate a reference to a bug so I can ask Fedora to patch their version of gcc.
