I just tried to compile a Suse Linux package with the GNU C++ compiler version 4.3 snapshot 20070302.
The compiler said utrie.c: In function 'utrie_open_3_4': utrie.c:51: error: invalid operand to binary operator (int) j_93; utrie.c:51: error: incorrect sharing of tree nodes vect_cst_.1224_132 = {(int) j_93, stmp_var_.1221_129, stmp_var_.1222_130, stmp_var_.1223_131}; (int) j_93; utrie.c:51: internal compiler error: verify_stmts failed Please submit a full bug report, with preprocessed source if appropriate.
