Description: from86 bug ... overwriting user memory
Component: Library
Date: Thu Apr 2 11:41:37 BST 1992
-----

The from86 function copies bytes from PC memory to the transputer
memory.

A bug exists in that a zero is appended to the end of the memory
region written on the transputer.  Thus, if the user has requested
1000 bytes from the PC and has allocated a 1000 byte array for these
bytes to be written to, then 1000 bytes will be written correctly
followed by a zero at location 1001, overwriting anything previously
there.

The implementation uses a sub-function which reads a string from the
server buffer and writes it to an array passed as a parameter.
Unfortunately this sub-function has side effects and writes an end of
string character after the end of the data just written.

A work-around is to allocate a buffer which is at least one byte
larger than required.  This problem will be fixed in the next release.
