[issue21167] float('nan') returns 0.0 on Python compiled with icc

[Hrvoje Nikšić]

Hrvoje Nikšić added the comment:

The compilation was performed with the default flags, i.e. without -fp-model strict or similar.

If Python requires strict IEEE 754 floating-point, it should probably be mentioned at a prominent place in the documentation. Administrators building Python with alternative compilers or on non-gcc Unix systems might not be aware of the issue.
