dc bug report

[Laurent Vogel]

Hello, this is a kind of bug report for gnu dc.

1) bug:

  $ echo 2 1:ala | dc
  dc: garbage in value being duplicated
  Aborted (core dumped)
  $ echo 2 1:aLa | dc
  dc: stack register 'a' (0141) is garbage
  Aborted (core dumped)

This is dc (GNU bc 1.06) 1.3, patched using the debian patch
named bc_1.06-12.diff.gz, compiled on cygwin by making:

  ./configure; make

(the bug also exists on the original dc (GNU bc 1.06) 1.3)

2) remark: <string.h> needs to be #included in both getopt.c 
(strcmp, strncmp, strlen) and number.c (memset, memcpy, strlen).

3) address bug-dc (at) gnu.org, seemingly aliased to
  ken (at) halcyon.com, reports "User unknown".

best regards,

Laurent Vogel
