[Bug middle-end/20623] ICE: fold check: original tree changed by fold with --enable-checking=fold

------- Comment #39 from rmansfield at qnx dot com  2009-08-12 14:22 -------
I came across a original-tree-changed-by-fold ICE building libsupc++ for a
arm-unknown-linux-gnu target with --enable-checking=fold.

gcc version 4.5.0 20090812 (experimental) [trunk revision 150681] (GCC)

../../../../libstdc++-v3/libsupc++/dyncast.cc: In function 'void*
__cxxabiv1::__dynamic_cast(const void*, const __cxxabiv1::__class_type_info*,
const __cxxabiv1::__class_type_info*, ptrdiff_t)':
../../../../libstdc++-v3/libsupc++/dyncast.cc:86:1: internal compiler error:
fold check: original tree changed by fold
