  segmentation fault when executing incorrect code (Message 1 to 3 of 3)

Hello all,

I encountered a segmentation fault in povray. By accident I wrote some 
incorrect code: 

	#if MyValue < MyFunction(A, B)

Which, of-course, should be written as:

	#if ( MyValue < MyFunction(A, B) )

The first code example gives a segmentation fault, while I would expect 
an error message saying that the code is not correct. Did I find 
something new, or is this already known behaviour?
I am using povray version 3.6.1 (g++ 3.4.1 @ i686-pc-linux-gnu).

I guess the issue /might/ have something to do with this known bug (that 
has been fixed in POV-Ray 3.7 beta 35 already, but not in the 3.6 branch 
yet):

Hi,

povray 3.7 beta 35 exits with the following message (which is like 
expected):

File 'input.pov' line 95: Parse Error: Expected '(', float function 'float
 identifier' found instead
Fatal error in parser: Cannot parse input.
Render failed
