Runtime failure in H5T__init_native_float_types()

[dkokron]

Describe the bug
I'm seeing a floating point exception while opening a NetCDF4 file with nf90_open(). A partial stack trace follows.

 forrtl: error (65): floating invalid

Hey,

I believe this might be related to #3831?

FYI: We experienced the same in conda-forge/code-aster-feedstock#57. I re-ran the compilation with hdf5=1.14.0 locally and the issue was gone.

Hopefully this will be fixed in 1.14.4 (which I believe has a milestone freeze today).

This should be fixed in 1.14.4, which releases today. The floating point exceptions are generated by our datatype introspection code, which runs at library startup. This used to be done in a separate program at compile time, but this made cross-compilation difficult, so now it's a runtime check.

Please reopen if this isn't fixed in 1.14.4 and we'll investigate further

[dkokron]

Just tested with the hdf5_1_14_4 branch. The "floating invalid" error is gone.
