[mapserver-users] 5.2 AGG and PHP mapscript problem - possible build issue?

Hi all,

I could really use some help on this one. This runs for some areas of 
the map but will segv for others which implies that the trigger is 
data/mapfile related, although this might be the root issue. I did fine 
a suspect warning during the compile of mapscript, see below, but not 
sure what to make of it or why it is happening.

The problem I am running into is that php/mapscript is crashing from 
what appears to be infinite recursion in an AGG function.

gdb /home/steve/bin/php
run precache-dbg.php -s=50000 -e=-17.8,10.0,65.0,39.8 -m=map2_en -r=42,43

and this goes on forever as far as I can tell.

If I run the same image via:

./mapserv 
QUERY_STRING='mode=map&map=/u/data/maps/en/ayna-master.map&mapext=48.026827464+29.4962617073+48.2833498244+29.7527840677&ingsize=1616+1616&layers=all&map.imagetype=agg/png24&map.debug=5' 
 >junk.png

It exits normally with a segv.

The system is Linux centos, it is a clean build on a i386 cpu.

./configure --enable-force-cgi-redirect --with-regex=system 
-with-gd=/usr --with-jpeg-dir=/usr --with-png-dir=/usr --with-zlib=/usr 
--with-freetype-dir=/usr --enable-gd-native-ttf --without-xpm 
--disable-xml --without-pear --with-pcre-dir=/usr 
--with-config-file-path=/u/tools/lib

I get the same error with 5.2-beta2 and 5.2-beta4 building:

I also just noticed the following warning during the compile:

This seems problematic, any thoughts on this or the other stuff?
