Hi, I tried the latest version of gcc from the stable 4.2 branch and noticed that gprof produces wrong data together with open -fopenmp for a C++ program. I have only two #pragma omp parallel statements in a class and the calling statistic of this class contructor is completly wrong (gprof tells me this constructor is called far too often). Is using OpenMP together with -pg -O0 -g supported? I found bug http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29935 related to OpenMP and profiling but it doesn't answer my question. Or could it just be a problem with the 4.2.1 snapshot? Jens
