first reported here:
https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/429113
The pow() function in the standard C library does not report a floating point
underflow exception like it is supposed to.
Compile the attached program with '-O0 -fno-bultin-pow -lm'. Then run it.
some people report correct behavior on x86 but not on x86_64
