Derek,

Hmm, this is somewhat odd.  Can you reproduce the problem with mapserv.exe
at the shell commandline or is it only when used under Apache?  I am wondering
if the Apache environment does not have the proper settings to find the
S-57 support files, though I would not expect that to result in a crash.

When you say things work with MapServer 5.0.2 but not 5.2.0, do you mean
within the OSGeo4W environment?  That is, does dropping back to the 5.0.2
version in OSGeo4W fix the problem again?

To enable the ECW and JP2ECW drivers you will need to install the gdal-ecw
plugin package:

Something when wrong when I tried to download the attachments so I haven't
seen them.   Once again, is this something that broke in moving from 5.0.2
within OSGeo4W to 5.2.0?
