thanks, that was what I had in mind.
The largest difference seems to be in "tree STMT verifier" (36% runtime
increase), a few others increased slightly, most seem to be nearly
identical. (This distribution could be an artifact of my example code, of

Is there any reasonably simple way to find out why the C++ version is
slower? I can use something like oprofile, of course, but I thought
gcc can
somehow give statistics about its internal times, which might be
more useful
for a first approximation.
I think you're thinking about the -Q opti

a 64bit 2.6.28 Linux system (Core 2 E8400), building single threaded
