../../../libgcc/libgcc2.c:553:3: internal compiler error: tree check: expected
tree that contains ‘typed’ structure, have ‘block’ in fold_checksum_tree, at
fold-const.c:14160
I get the same results when setting CC and CXX to be gcc-4.4 and g++-4.4
respectively (the default system compiler on Ubuntu 11.10 is 4.6.1-based).
Running the commandline that causes the ICE with -O1 also elicits the problem.
Setting BOOT_CFLAGS and CFLAGS to -O1 doesn't help matters.
