Marin, the intel-linux-9.0 failure:
looks like segfault or something like that -- no errors messages, and non-zero return status. Can you run the test manually and tell what's going on?
segfault.
No helpful output from strace.
I'm not sure but it looks to me as though the random lib has a few problems, I've run the tests on Linux/Itanium and Linux/Xeon using the HP testdrive machines, and there are (different) failures on both. The logfiles are attached, but the segfault has the following backtrace: (gdb) run Starting program: /house/maddock/bin.v2/libs/random/test/random_test.test/intel- linux/debug/random_test Running 1 test case...

I can reproduce this with just #include <cmath> int main() { long double d = std::tan(-0.53682426991417537756471137222469281L); return d; } So I'll file a bug report with Intel. HTH, John.
