I'm trying to write a test to check I get all the subnormal

The usual thing to do with a new test is to try it on a known good
platform. Unfortunately, the x86 processor of my workstation is
actually
known to get these calculations wrong. Could someone with a fully
ieee compliant FPU try this test?
Just use -mfpmath=sse -msse2 to force use of SSE instructions
for double precision math. Should be the default nowadays, IMO.
