[Bug debug/30986] New: [4.0/4.1/4.2/4.3 regression] ICE in splice_child_die

["schwab at suse dot de" <gcc-bugzilla at gcc dot gnu dot org>]

The test gcc.c-torture/execute/mayalias-2.c is causing an ICE when compiled
with -g.  The failure can be reproduced as far back as gcc 4.0, but gcc-3.3
works.

$ ./xgcc -B./ -g -c ../../gcc/testsuite/gcc.c-torture/execute/mayalias-2.c 
../../gcc/testsuite/gcc.c-torture/execute/mayalias-2.c:2: internal compiler
error: in splice_child_die, at dwarf2out.c:5589
