mapserv segfaults

[Steve Lime]

Post the mapfile! That might really help. Are you using the REQUIRES or
LABELREQUIRES parameters? There's been a report of segfaults with those
(and I'm looking for examples so to fix).

Hi Steve,

thanks for the prompt response and the suggestion.

gdb is just telling me the error occurred in memory allocation, but this
is not helping me much:

(gdb) run
Starting program: /extra/contrib/apache/cgi-bin/mapserver-4.4.1
[Thread debugging using libthread_db enabled]
[New Thread -1218617216 (LWP 8708)]

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1218617216 (LWP 8708)]
0x039ba0d1 in realloc () from /lib/tls/libc.so.6

I was hoping to tell what request parameter or map configuration element
might be causing trouble. Can you think of any way for me to pursue this
at a higher level?

Thanks!
