There are many gomp failures in http://gcc.gnu.org/ml/gcc-testresults/2007-04/msg01353.html
On both Linux/ia64 and Linux/x86-64, I saw many failures like Executing on host: /export/build/gnu/gcc/build-x86_64-linux/gcc/testsuite/g++/../../g++ -B/export/build/gnu/gcc/build-x86_64-linux/gcc/testsuite/g++/../../ /net/gnu-13/export/gnu/src/gcc/gcc/gcc/testsuite/g++.dg/gomp/block-0.C -nostdinc++ -I/export/build/gnu/gcc/build-x86_64-linux/x86_64-unknown-linux-gnu/32/libstdc++-v3/include/x86_64-unknown-linux-gnu -I/export/build/gnu/gcc/build-x86_64-linux/x86_64-unknown-linux-gnu/32/libstdc++-v3/include -I/net/gnu-13/export/gnu/src/gcc/gcc/libstdc++-v3/libsupc++ -I/net/gnu-13/export/gnu/src/gcc/gcc/libstdc++-v3/include/backward -I/net/gnu-13/export/gnu/src/gcc/gcc/libstdc++-v3/testsuite/util -fmessage-length=0 -fopenmp -fdump-tree-omplower -S -m32 -o block-0.s (timeout = 300) /net/gnu-13/export/gnu/src/gcc/gcc/gcc/testsuite/g++.dg/gomp/block-0.C: In function 'void _Z3foov.omp_fn.0(void*)':^M /net/gnu-13/export/gnu/src/gcc/gcc/gcc/testsuite/g++.dg/gomp/block-0.C:28: internal compiler error: in calc_dfs_tree, at dominance.c:374^M Please submit a full bug report,^M with preprocessed source if appropriate.^M See <URL:http://gcc.gnu.org/bugs.html> for instructions.^M compiler exited with status 1 -- Summary: [4.3 regression] gomp is broken Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgomp AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: hjl at lucon dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31722
