Description

While doing a jprt run for some libraries changes for the 6-open release, I run the the unrelated math libraries tests too including
test/closed/java/lang/Math/HyperbolicTests.java

This test failed on linux_x64-fastdebug-c2 with a bad sign of zero in some cases.

This is a build 19 JVM so presumably the same failure exists there too.

EVALUATION

Fastdebug build does compile s_tanh.c with oprimization
and generates incorrect code.
