OK, I can break it on HP aCC with:
maddock_at_td176> aCC -AA -Ofaster -I../ -I ~ *.cpp
Assertion failed: (fpclassify)(x) == FP_SUBNORMAL, file test.cpp, line 122
ABORT instruction (core dumped)
However the docs for -Ofaster do indicate that denorms don't work correctly,
so it may be that problem here :-)
g++ on HP-UX looks OK.
On Linux/IA64, with Intel C++ 9.1
maddock_at_[hidden]> icc -O3 -I.. -I ~ *.cpp -static
a.out: test.cpp:139: void <unnamed>::test_basic() [with T = float]:
Assertion `(fpclassify)(x) == FP_SUBNORMAL' failed.
Intel on IA32 looks OK, though I didn't try very hard to break things :-)
And I couldn't find an AMD64 machine with Intel for EM64 installed to test
