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
