internal compiler error

[romanis%gmx.ch@localhost]

hello again,

in order to track down a internal compiler error, i've tried to simplify a 
source file, until i have a minimal piece of code.

unfortunatly it's not as easy as i expected :-(
the source code i use will generate a internal compiler error, if i compile it 
with -O1. But if i remove another line (which can be completly irrelevant for 
the logic) it will compile cleanly.

i've uploaded my attempt to:
http://ec2-54-228-13-95.eu-test-1.compute.amazonaws.com/test.c

maybe it is small enough and someone with some gcc knowledge can use it for 
fixing that bug.


i've used NetBSD-6-stable for my tries.


# gcc -g -O1 -c test.c
test.c: In function 'ccache_lookup':
test.c:95: internal compiler error: in change_address_1, at emit-rtl.c:1819
