Quad FX library_function causes stack trace

[Hans-Peter Sorge]

Hi,


⎕FX  'library_function'     should probably return 'Domain Error'


      'libedif2.so' ⎕fx 'edif2'
edif2


⍝ just happened to be an accident ...

      ⎕fx 'edif2'

==============================================================================
Assertion failed: old_ufun
in Function:      fix
