So, in a bit of haste, I ran my scene with

#declare Inverse = function (x, y, z, R, S) {log( 1-Inverse(x,y,z,R,S) )}

which of course calls itself, and POV-Ray issued a warning and stopped, but it
also became unresponsive and gave me this in the terminal window

*** Error in `qtpovray': realloc(): invalid old size: 0x00007f580801dcd0 ***
*** Error in `qtpovray': malloc(): memory corruption: 0x00007f580801d420 ***

Just throwing that out there.

WORKSFORME

Can you post a whole scene that tips over?

----------
#version 3.7;
#declare Inverse = function (x, y, z, R, S) {log( 1-Inverse(x,y,z,R,S))}

Possible Parse Error: assumed_gamma not specified in this POV-Ray v3.7
or later scene. Future versions of POV-Ray may consider this a fatal
error. To avoid this warning, explicitly specify 'assumed_gamma 1.0' in
the global_settings section. See the documentation for more details.
