[comp.sys.ibm.pc] PKARC v2.0

I have encountered a bug in PKARC/PKXARC v2.0 that I thought I should
mention so that it gets fixed someday.

I run a Fido here in Ottawa and I have this one user that is testing/using
a new communications program.  Due to a bug in the xmodem protocol in the
program the zero byte that is supposed to follow the last ARChive header
marker (0x1A) is occasionally dropped and the remainder of the block is
filled with ASCII EOF (also 0x1A).  If PKARC is instructed to "view" the
archive, it correctly displays all the file headers and then reports that
the file is not an ARChive -- understandable I suppose.  If you proceed and
attempt to extract all files, PKARC will quite happily do so until you get
past the last file.  At this point, PKARC runs into some trouble and rather
than admit it hangs the machine without even reporting a reason.

I have only had this problem with ARChives uploaded by this particular
user, but thought I should mention it.  Any other outstanding bugs I should
watch out for?
