[Bug c/37756] New: ICE building object file with -O3 and -combine

Mon, 06 Oct 2008 14:24:51 -0700 

# gcc *.i -combine -O3 -c -o udns.o
dia-submit/udns_init.c: In function ‘dns_set_srch_internal’:
dia-submit/udns_init.c:47: internal compiler error: in
get_addr_dereference_operands, at tree-ssa-operands.c:1698

Because it only appears to happen when building with multiple input files, I
have attached a tar of .i files that reproduce the problem (the udns async DNS
resolver library actually).

I have observed this ICE on i386 and x86_64 and IA64 builds of GCC 4.3.2.
