C source code
The attached C code, with recent gcc trunk and compiler flag -O2,
does this:
during GIMPLE pass: strlen
iplookup.c: In function ‘iplookup_router_entry’:
iplookup.c:148:1: internal compiler error: in decompose, at wide-int.h:984
0x5da4cc wi::int_traits<generic_wide_int<wide_int_storage> >::decompose(long*,

The problem first seems to occur sometime between revision 278950
and 279000.
Reducing the code now.
