I pushed something else for you to try. clang reportedly supports
feclearexcept from the C standard. Maybe it supports it better than
_clearfp. I have pushed a version that uses feclearexcept if the
symbol __STDC_IEC_559__ is defined. I read rumors than clang sets
this symbol, but I can't check. The code is at j.h:529. If the
symbol is not defined, replace the test with #if 1 to force clang to
use feclearexcept , and see if it makes things better.

Did you check out the latest push to see if that makes any difference?

clang with -O0 fixes it too.

Building with gcc works ok. I'll try clang/-O0

Just a guess, recently we switched from gcc to clang. clang is
too smart in
optimization that it short circuit some code that deals with
NaN, I've put
some inline asm to teach clang register flags need checking.
This works in
the past.
Can you try build and test with -O0 or with gcc?

This baffles me. I wonder if there is some compiler
interaction with
_clearfp(). In case so, I have pushed out another change that
puts a
couple of memory fetches between the clearfp()s. Would you
please build
that & report back? If it fails on the same line, please try
the two
parts individually & see if they both fail.
