Unfortunately, I don't have a Mac to investigate this, so we'll have
to look if someone else wants to try their luck.  Do you have at least
an error message?

Yes, I think so.

Re: Flexi-streams test suite failing on OpenMCL

Hi Edi--

the error message is

value 1509 is not of the expected type (UNSIGNED-BYTE 8).
   [Condition of type TYPE-ERROR]

If you'd like me to try anything, or could point to an area of
investigation, let me know

regards

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.

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

CCL::SHARED-RESOURCE: NIL
CCL::IOBLOCK: #S(CCL::FILE-IOBLOCK :STREAM #<FILE-BINARY-INPUT-STREAM

                                   :INBUF #<IO-BUFFER  (UNSIGNED-BYTE
                                                        8) 3/2048/2048
#x85576F6>
                                   :OUTBUF NIL
                                   :ELEMENT-TYPE (INTEGER 0 255)
                                   :ELEMENT-SHIFT 0

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.
