Now I can't find where it's dropping the core file. The one generated before recompiling bash has this backtrace (when loaded with the new bash)
#0 0x0005a5f8 in list_length () #1 0x000803cc in strvec_from_word_list () #2 0x000230d4 in execute_disk_command () #3 0x00023a68 in execute_simple_command () #4 0x00021630 in $a () #5 0x00021630 in $a () Previous frame identical to this frame (corrupt stack?)
