The problem with popper reported here last week is real, and serious.  It
appears to have been introduced into popper around September, 1990.  It
would occur if you had compiled popper with -DDEBUG, and then run popper
without the "-d" (debug) flag.

If you compiled popper without -DDEBUG then you are not vulnerable to this
particular bug.  Unfortunately, the Makefile in the popper-1.7.tar.Z file
has -DDEBUG set as the default.

I have changed the default in the makefile in popper-1.7.tar.Z in the ftp
repository.  There is also a popper-1.81beta.tar.Z there which fixes two
other problems.  I believe 1.81 is stable, but will wait for some time
before removing the 1.7 file.

The ftp repository is ftp.CC.Berkeley.EDU.  Its current addresses are:
128.32.136.9, 128.32.206.9, 128.32.206.12, 128.32.136.38.
