Hmm, and this happens in the STREAM-READ-CHAR method?  Could you try
to figure out what part of the program generates the 1509?

Re: Flexi-streams test suite failing on OpenMCL

Hi Edi--

the SLIME inspector gives me this for the flexi-stream, and 1509=0x05e5 which is
"HEBREW LETTER FINAL TSADI".  It looks like OpenMCL is attempting to read
unicode rather than raw bytes.  Hmm...

An object.
 [type: FLEXI-STREAMS::FLEXI-UTF-8-INPUT-STREAM]

Very strange.  Could you confirm in the inspector that the underlying
stream is really a binary stream with element type (UNSIGNED-BYTE 8)?
And (using the debugger - I think, IIRC, you press v on the top frame)
could you try to find the exact place where the error occurs?

Here's the description of the underlying stream from the slime
inspector -- I can't
inspect this stream itself in slime...

#<FILE-BINARY-INPUT-STREAM

Wrapper: #<CCL::CLASS-WRAPPER CCL::FILE-BINARY-INPUT-STREAM #x810DDF6>
Instance slots
CCL::DIRECTION: :INPUT
CCL::CLOSED: NIL
CCL::SHARED-RESOURCE: NIL
CCL::IOBLOCK: #S(CCL::FILE-IOBLOCK :STREAM #<FILE-BINARY-INPUT-STREAM
("home:src;site;flexi-streams-0.11.2;test;hebrew_utf8_lf.txt"/10)
#x8557786>
                                   :UNTYI-CHAR NIL
                                   :INBUF #<IO-BUFFER  (UNSIGNED-BYTE
                                                        8) 3/2048/2048
#x85576F6>
                                   :OUTBUF NIL
                                   :ELEMENT-TYPE (INTEGER 0 255)
                                   :ELEMENT-SHIFT 0
                                   :CHARPOS 0
                                   :DEVICE 10

That looks correct.

No, I meant where /in/ STREAM-READ-CHAR.  Doesn't SLIME locate a
particular form in the function's definition?  (Maybe it can't due to
the macrology, dunno.)

Thanks,
Edi.
