Re: Segmentation fault on startup for v200 on FreeBSD --- resolved

Summary:
Solved my problem. It was being caused by mismatched binaries.

Thanks Richard for your help.

I found docs for gdb via: info gdb

This was enough to get me started with the debugger. Next I fooled around
trying to get mzscheme to run under the debugger.  In doing this I discovered
that the filed called "mzscheme" in the bin directory is the script you
described above while the "mzscheme" in the .bin directory is the real binary.

When I ran the binary directly in the ./bin directory it didn't seg fault. So I
opened up the script to see what it was doing and discovered that the PLTHOME
variable was pointing to a directory that actually contained v103 binaries
instead of the v199 binaries I had just built.  I deleted the v103 directory
reran make install and edited my .cshrc file and now everything works.

Thanks again
