Okay, so the backtrace looks like this: 483 switch (e - p) { (gdb) bt #0 0x005380c0 in search_nonascii (e=<optimized out>, p=<optimized out>) at string.c:483 #1 coderange_scan (p=<optimized out>, len=<optimized out>, enc=0x63d698) at string.c:505 #2 0x00538866 in rb_enc_str_coderange (str=6750060) at string.c:634 #3 0x00538920 in rb_str_hash (str=6750060) at string.c:3112 #4 0x0052fb94 in do_hash (tab=0x63fe20, key=<optimized out>) at st.c:1479 #5 st_update (tab=0x63fe20, key=<optimized out>, func=0x539fb8 <fstr_update_callback>, arg=2080371772) at st.c:1479 #6 0x00534c46 in register_fstring (str=6750060) at string.c:341 #7 0x0054e06a in register_static_symid_str (id=33, str=<optimized out>) at symbol.c:417 #8 0x0054e458 in register_static_symid (enc=0x63d698, len=1, name=0x7bfff47f "!\\\bI", id=33) at symbol.c:407 #9 Init_op_tbl () at symbol.c:46 #10 Init_sym () at symbol.c:86 #11 0x0049085c in rb_call_inits () at inits.c:21 #12 0x00472c86 in ruby_setup () at eval.c:61 #13 0x0047444c in ruby_init () at eval.c:78 #14 0x00418e76 in main (argc=<optimized out>, argv=<optimized out>) at ./main.c:41 (gdb) I will probably have to rebuild with debug symbols disabled so we can see more.
