[mapserver-users] PHP: Segmentation fault when draw() orsaveWebImage()

[Burgholzer,Robert]

Pavel,
So... the trouble is actually with the rasters, not with the Mapserver version?  As evidenced by the fact that now neither the previous nor the current version of mapserver work for you?  Couple of questions:

1. Can you render this map from the mapserver CGI?
2. Did you recompile PHP, mapserver, and the PHPMapscript with the same options?  Perhaps there is a missing option pertaining to the raster graphic format?

HTH,
r.b.

Hi Robert,

Thanks for advice. But downgrade to the same version of PHP &  
Mapserver (ie 5.0.0) as before don't solve my problem. (the version of  
apache was chenged because of security issues).

So now is working one collection of 3 maps in one mapfile and not  
working collection of 3 maps in one mapfile too... (but 90 % of load  
is targetting not working maps).

When I comment out all raster layers it's working. (reference map,  
scale bar, grid and drawned points on the map).

When I commnet out only some of raster layers, it works on 33% (once  
yes, 2 times not). I increase amount of allowed memory in php.ini file  
(to 1024M) but without any visible effect.

Bye
Pavel
