[cl-ppcre-devel] Bug when loading file in SBCL x86-64

[Liam M. Healy]

See http://paste.lisp.org/display/5474.
This simple form fails to load correctly in SBCL x86-64.  There is no
problem with the 32 bit compiler.

(defun test (line)
    (cl-ppcre:scan-to-strings
     "Location:.*( \\d+\\.\\d+) *(\\w).*( \\d+\\.\\d+) *(\\w)"
     line))

Compile, load the file:

debugger invoked on a TYPE-ERROR in thread 24956:
  The value NIL is not of type HASH-TABLE.


Consensus is that it's a bug in cl-ppcre

(11:03:28) Xof: LiamH: bug in cl-ppcre; please report it to edi weitz
(11:09:08) Xof: "Works fine in sbcl/ia32 and ACL/ia32.", hmm, maybe
it's not a bug in cl-ppcre 
(11:09:57) chavatar: Xof: if you read the backtrace, the
object-not-hashtable problem is coming from PCL guts 
(11:10:30) chavatar: .. or maybe not
(11:10:46) chavatar: it could be either PCL or CL-PPCRE
(11:13:53) Xof: no, the object-not-hashtable is coming from the :after
char-class method which does hash-table-count on (getf :hash args) 
(11:14:21) chavatar: ok
(11:17:26) Xof: if it helps, it's failing on the sixth initialization of a char-class object
(11:18:11) Xof: and, um, indeed I'm sure now
(11:18:38) Xof: because the second call to make-instance 'char-class in CONVERT-AUX can explicitly pass :hash nil
(11:18:42) Xof: so, bug in cl-ppcre


Thanks,
