Hello,
This error message appears in Povray when I try to render a truetype font
called "Bach", using Moray:

Parse Error: Attempt to malloc zero size block (file: ..\
..\source\truetype.cpp line: 1275)

What does it mean? It refers to "truetype.cpp". There is no such file
anywhere on my computer. Does anyone know what it is?
Also, when it does this it disables both Povray and Moray and anything else
running in Windows until I use alt-ctr-del to shut it down.
Any help would be appreciated.

Thank you,
Steve Shelby

  It means that an unexpected error happened (one could call it a bug). This
is a problem in the source code of POV-Ray and it's nothing you can remedy
by yourself (unless you fix the problem in the source code, of course).
  Trying to allocate a 0-size block is always a sign that some sanity check
is missing.

  If this happens in the latest 3.5beta, you should post a proper bug report
to povray.beta-test

Warp,
The problem I described is in Povray 3.5. I just tried the same thing using
Povray 3.1 and got a slightly different error message:

tex.pov:85: error: Attempt to malloc zero size block (File: ..\..\TRUETYPE.C
Line: 1212).

And with 3.1 the system doesn't lock up. What do you make of that?

Steve

Then definetly you should report bug in povray.beta-test with optionally some
binaries in povray.beta-test.binaries group.

Actually, it is a corrupted font file and POV-Ray doesn't catch the problem
early enough.  In the particular font file there is an empty kerning table.

Thorsten,
Is there any way I can fix that myself, or am I just out of luck with that
font?
Hmm... I just realized that I was able to use that font sucessfully a couple
months ago, before I had to replace my hard drive and re-install everything.
Maybe I should try a new download of the font?
Steve

Loading it into a font editor and saving it again might help.  As for font
editors, maybe there are some in the links list.

As for the bug in POV-Ray, in the next beta or so it will just issue a clear
text error that the font file is corrupted rather than the internal error.

Nope, I never added any.
