I tried to reduce the testcase, but the problem just disappears on
unrelated changes of the code.
A run through valgrind resulted in the following output:

The uninitialised value is reported long before the ICE happens, but
maybe it's the culprit anyway. An uninitialized value would also explain
why unrelated changes make the code compile again.

The failure disappeared again for me on 20050712, but given comments about
uninitialized memory I doubt this indicates a fix.
