[mapserver-users] wrong tileindex path make mapserver 6 crash

[Jeff McKenna]

I know last week on the Windows benchmarking server for FOSS4G I made 
some mistakes with tileindex paths for rasters, with MapServer 6.1-dev 
and shp2img, and there was no crash (I used the -all-debug switch to get 
the error messages from MapServer).  Maybe this is a platform-specific 
issue? not sure.
