Hallo,
I've got a file open for IO. Only writing to it works okay. But if I
also try to read from it, then things start going wrong. I've attached a
test case that should return NIL but instead raises an error in ABCL
(1.3.3, on OSX).
The problem is with the call to #'write-sequence on line 21.
In fact, from some other tests, I believe that replacing that call to
#'write-sequence with a call to a function that does the same thing but
by repeatedly setting the file-position and writing a byte, for each
byte in the sequence, fixes things. That means something about
#'write-sequence is broken.
Maybe I misunderstand the file level functions in Common Lisp, and my
test doesn't use them correctly. However, the test passes in: CLISP,
CCL, CMUCL, SBCL, ECL. So I thought I'd report this, just in case it is
a bug in ABCL.
Also, removing the last three lines of code in #'main, which read one
byte, makes the test run without errors.
