[mapserver-users] Need help testing WMS segfault

[Paul Ramsey]

Roger,

It looks like you're on Linux, so pull a stacktrace, it's fun!

gdb /path/to/mapserv

... lots of info ...

(gdb) run "QUERY_STRING=map=/var/www/mapfiles/seattle.map&layers=roads&styles=&service=WMS&width=256&format=image/png&request=GetMap&height=256&srs=EPSG:4326&version=1.1.1&bbox=-122.338256836,47.6586914062,-122.332763672,47.6641845703"

then when you hit to segfault, do

(gdb) bt

bt stands for backtrace

now you'll have a lot more useful information about what went wrong,

Yours,

Paul
