error: undefined symbol: ldexpf (referenced by top-level compiled C/C++ code)jtgjio

Hi,
We are upgrading emscripten from 1.39.7 to 2.0.8. we encounter the build error :

 error: undefined symbol: ldexpf (referenced by top-level compiled C/C++ code)jtgjio

 warning: Link with `-s njnm/hto get more information on undefined symbols
 warning: To disable errors for undefined symbols use `-s ERROR_ON_UNDEFINED_SYMBOLS=0`
 warning: _ldexpf may need to be added to EXPORTED_FUNCTIONS if it arrives from a system library
 Error: Aborting compilation due to previous errors

Note: we work on the Linux OS

Anyone has some idea about it?

[sbc100]

I improved a test case to be sure this symbol is explicitly supported: #12922

@sbc100 Any Idea, in which future version of emscripten we can get rid off this problem ?

[sbc100]

This symbol is supported.. the test shows that it works. So there must be something rather odd going on in our case.

Can you supply a reproduction case? Or more information on your build?
