Hi

I found this whilst making some modifications to Gilles' makegrass macro but
it's hard to put into words, so I'll give an example.. If you have

#declare fname1="reedsmsh1.inc" // mesh include file
#declare objectPatch=#include fname1

then all works fine. But, if fname1 hasn't been defined then POV gives the
expected error message "string expression expected but undeclared identifier
'fname' found instead' but POV then crashes with the following error message

MEGAPOV07 caused an invalid page fault in
module MEGAPOV07.EXE at 0167:004d733e.

I've tried this in windows versions of both MegaPOV 0.7 and POVMan 0.71.4.
I'm running Windows 98 SE on a P133 with 32mb ram. Can anyone confirm this?

Hi, well it seems that it isn't quite that simple. I'm trying to cut my
scenefile down to see what the culprit is, hopefully have the proper reson
soon.

Hi

Well it seems to happen only if you have two files set up like this:

// Start of crash.pov

#include "crash.inc"
#declare object=#include fname

// End of crash.pov

// Start of crash.inc

#macro Crash(fname)
#end

// End of crash.inc

I've checked with the official POV and it works fine. I hope this helps, it
took me a lot of hunting to find it.  :)
