Two lines cause a stable crash at both POV 3.5 b9  and  POV 3.1g
on P-160 32 Mb Win98  and  PIII-1000 512 Mb Win2000  :
//-------8<----------
#macro Gen
Gen()
//-------8<----------

First discovered with more lines of code between them.

I can confirm it
POV 3.5 b 9 on PII 233 128 MB with NT 4 Sp 6

> #macro Gen
> Gen()

but

#macro Gen()
Gen()

works fine and causes parse error

It causes crash only for the same token.
Following scenes generates only parse error:

First:
  #macro Gen Test()

Second:
  #macro Test()#end
  #macro Gen Test()

Third:
  #macro Gen() Gen()

Fourth:
  #macro Gen Gen
