Right, it's the same /vol/gcc/src/hg/master/local/libstdc++-v3/testsuite/26_numerics/headers/cmath/equivalent_functions.cc:199: void test_long_double_overload(): Assertion 'std::cosh(x) == std::coshl(x)' failed. that you saw on S11.3. Again, only __coshl called in there.

That looks like a similar problem though. std::asin(float) probably calls std::__asinf, which apparently gives a different result to ::asinf. If you comment out the call to test_float_overload() in main, it might fail at the same place in test_long_double_overload (or maybe somewhere else!) > I wouldn't worry too much about the 11.3 failure (if it's 11.3-only): 11.3 > support is deprecated and was supported to be removed from trunk before the > GCC 14 release.

Yeah, the cfarm is the only way I can test on Solaris, so that's why I use 11.3 with -enable-obsolete.
