I have seen this as well, usually when I do a Ctrl-C on a
terminal session over a PPP link to my office. This is both with and
without asyncmap set to escape control characters. It may not be a
bug in "other ppp implementations". See the following from the
Changelog of PPP 2.3.4:
* Fixed some bugs in the linux driver and deflate compressor which
were causing compression problems, including corrupting long
incompressible packets sometimes.
Perhaps this is what we are all seeing?
