bug in GCC 4.4 with OpenMP (internal error)

view full story

http://forums.fedoraforum.org – I'm using GCC with OpenMP since some years now. I find now in a Fedora 11, x86_64 system (GCC 4.4) that compiling the following code gives an internal error. Code: ------ gccbug.cpp ------- #include <cstdio> #include <omp.h> void f() { #pragma omp parallel   {     int jx=-1, foo;     while (1) { #pragma omp critical       {         foo = 23;         printf("hahaha \n");       }       if (jx==0) break;     }     // foo = 45;   } } ---------------- [mstorti@galileo mgwomp]$ g++ -fopenmp -c -o gccbug.o gccbug.cpp gccbug.cpp: In function 'void f()': gccbug.cpp:18: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <http://bugzilla.redhat.com/bugzilla> for instructions. Preprocessed source stored into /tmp/ccIPB69w.out file, please attach this to your bugreport. [mstorti@galileo mgwomp]$ Of coursem the code does nothing, it comes from a mathematical program that I'm trying to speed up with OpenMP and when I found the error I simplified the code, arriving to the snippet above. I found that the error disappears and the code is corretly compiled if 1./ The printf line is uncommented. 2./ The line foo=45 is uncommented. 3./ The "#pragma omp" lines are commented. Also, the same code compiles OK in a Fedora 9 system (GCC 4.3). Should I report this bug at bugzilla.redhat.com? Regards, Mario PS: some more data follows.
