mapserver segfaults on x68_64 intel xeon

[Umberto Nicoletti]

Send us the stack trace (run the backtrace command from gdb) so that
we can see what mapserver is doing when it crashed and report the
configure flags.

I suspect the issue has something to do with international charsets,
so report also the values of the LANG and LC_* variables.
