[Gcl-devel] BUG: C identifier allocation causing compilation error

[Eric Marsden]

Hi,

GCL 2.7.0 compiled from CVS on Linux/AMD64 is not able to compile the
code shown below, with an error during C compilation. Looking at the
generated C code, it seems that the generation of C identifiers is
buggy.

,---- arr7.lsp
| (defun bench-string-concat (&optional (size 1000000) (runs 100))
|   (declare (fixnum size))
|   (dotimes (runs runs)
|     (let ((len (length
|                 (with-output-to-string (string)
|                   (dotimes (i size)
|                     (write-sequence "hi there!" string))))))
|       (assert (eql len (* size (length "hi there!")))))
|     (values)))
