DESCRIPTION

Invoking bzrto with the following options
  
   % bzrto -verbose -metafont gbbb30b -output=gbbb30B

dumps core with a segmentation violation when writing the Metafont
epilogue.  The failure occurs in the function "output_ligtable" while
writing ligature information, caused by a pointer dereference that occurs
before the data is tested for validity (in a local variable
initialization).

SUGGESTED FIX

Making the following change to bzrto/metafont.c corrects the problem:

bzrto/metafont.c
415c415
<       tfm_char_type *c;
---
>       tfm_char_type *c = CHAR_TFM_INFO (*(chars[code]));
422,424c422
< 
<       c = CHAR_TFM_INFO (*(chars[code]));
< 
---
