[Bug c/31962] New: ice for legal code with -Wall -O2

[dcb314 at hotmail dot com]

I just tried to compile Suse Linux package icecream-0.7.14a-5 with the GNU C 
compiler version 4.3 snapshot 20070511

The compiler said

minilzo.c: In function '_lzo_config_check':
minilzo.c:2162: internal compiler error: tree check: expected tree that
contains 'decl common' structure, have 'struct_field_tag' in ffan_walker, at
tree-ssa-alias-warnings.c:638
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Pre-processed source code attached. Flags -Wall -O2 required.
