I just tried to compile Suse Linux package ddiwrapper-0.2-86 with the GNU C compiler version 4.3 snapshot 20070803.
The compiler said write_msft.c: In function 'ctl2_alloc_string': write_msft.c:562: internal compiler error: tree check: expected ssa_name, have symbol_memory_tag in is_old_name, at tree-into-ssa.c:566 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions. Preprocessed source attached.
