Well I tried to reduce the scene still more and it seems that the 
content of the macro doesn't really matter...
Here is the minimal scene I've got :

//begin crash.inc
#macro Trans() #end
//end crash.inc

//begin crash.pov
//including the file makes POV-Ray crash
#include "crash.inc"

//if the content of crash.inc is included inline, normal behaviour:
//#macro Trans() #end

Trans()

#if(UndeclaredId) #end
//end crash.pov

Seems that it has to do with the parsing of macros in includes...

Here is the output I have in Debian Linux, kernel 2.6.11.6, 256 MB RAM, 
Pentium M 1.5 GHz :
