(Dang, committed 3 or 4 minutes too late or 6 or 7 minutes too soon for 
a really neat pre-release tag number ;))

Please try this - I hope it solves the crashes:

development is now driven by numerology?!  :-)

Known issue:

User-defined functions may cause a hard crash on some platforms.

If you encounter this issue, pelase copy 
`source/parser/parser_function_utilities.cpp` from the current master 
branch.

The Windows binaries appear to be unaffected, so I'm not rushing out a 
new version for now.

I've tried with two scenes, one crashes, the other does not.  the only
difference, afaict, is that the first uses array syntax in both declaration and
in one of the function components, while the second has no array stuff.

Then the recommended workaround probably applies to your system and, by 
extension, presumably Unix systems in general.

ok.  do you have a 'wget'able url for that file, please?

btw, the alpha (also) crashes when there's an "old-style" text primitive, ie
without cmap {}, irrespective of charset present in global_settings.  does the
above workaround fix that too?


regards, jr.

I have no idea what a "'wget'able" URL is, but maybe this one qualifies:

https://raw.githubusercontent.com/POV-Ray/povray/master/source/parser/parser_functions_utilities.cpp

I thought you were confirming that v3.8.0-alpha.10011104 fixed your 
issue? Please clarify, and double-check the version you're running.

Those `text` primitive crashes you were observing are totally unrelated 
to the user-defined function crashes.

will do nicely.  thanks.

yes, I appreciate that.

I used a reduced version of the 'pav-patt.pov' for the test, with the latest (ie
10011104) alpha.  it crashes when T2 "visible":

#version 3.8;
global_settings {assumed_gamma 1}

#declare S = "abcdef";

#declare T1 = text {
  ttf "arialbd.ttf" cmap { 1,0 charset 0 }
  S
  0.001 0
  pigment { color rgb<1.0, 0.6, 0.2>*1.25 }
  no_shadow
};

#if (0)
#declare T2 = text {
  ttf "arialbd.ttf"
  S
  0.001 0
  pigment { color rgb 0.1 }
  no_shadow
};
#end

Heh, don't expect me to know about any of that; I'm a Windows jockey and 
mouse pusher ;)
