No luck!-(I get 'No symbol "fcode" in current context.' and if not '<value optimized out>'). The only things I have been to print stepping through streamer_get_builtin_tree (ib=<value optimized out>, data_in=<value optimized out>) are (gdb) s streamer_read_uhwi (ib=0x7fff5fbfd820) at ../../work/gcc/data-streamer-in.c:93 93 { (gdb) p *ib $4 = {data = 0x142090d84 "\037", p = 1432, len = 1621}
