I've been working on getting a stable NetBSD version of the latest Kermit.

Something to the effect that C-Kermit 6.0, which has been built successfully
on hundreds of different UNIX and non-UNIX platforms (i.e. combinations of
OS, OS version, hardware, C compiler and version, etc) has this problem with
NetBSD (version xxx) using gcc (version xxx), in which, if it is built with
the -O (optimize) compiler switch, then the call stack is mangled, and after
a few function calls, a routine returns to never-never land and dumps core.
In the version I (i.e. you) built, this happens in the setlin() routine in
ckuus7.c, and the core dump occurs when you give a command like:

  set line hostname:socket

The makefile has been modified to omit optimization, and unoptimized binaries
-- which seem to work fine -- are being distributed.

I'm on NetBSD 1.2, which has gcc V2.72.  This bug also got me on a FreeBSD
2.0.5 system, which probably has gcc 2.4.6(?).

Anyone have suggestions how to isolate an optimization-type bug?

They keep telling me, "Shhhhh!"
