Hey gang,
I wanted to see if I'm missing something obvious before I file a bug on
this. With svn r181272, I am doing:
$ ../configure --enable-bootstrap --prefix=/home/matt
--enable-languages=c,c++ --enable-stage1-checking=all
[...]
$ make
[...]

../../../../libgcc/libgcc2.c: In function __muldi3:
../../../../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:13996
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.
Am I missing something, or is this a real bug?
Thanks!
