Package: cl-png
Version: 0.4-1
Severity: important
When I try to use cl-png with SBCL 0.8.19:
(png:decode-file ".../something.png")
I receive the following error:
The value #\Ó is not of type BASE-CHAR.
[Condition of type TYPE-ERROR]
Restarts:
0: [ABORT] Abort handling SLIME request.
1: [DESTROY-THREAD] Destroy this thread (19422)

...
The problem is apparently in the function PNG::DECODE-IDAT, which
converts binary data to strings and back in order to be able to call a
ZLIB-FROM-CL-PDF function. Perhaps using zlib.cl, which is a native
Common Lisp library not messing with strings, or utilizing cl-inflate
would be a better idea?
