The mapser version is 3.6.5 and was compiled with gcc. But the 
installation is _very_ - er - unusual. The people owning the server 
want everything mapserver related to be seperate from their 'normal' 
environment - incl. the libs. So I got a '/somedir/mapserver/local/' 
where libs and includes used by mapserver are stored. 

Moreover because they report problems adding the GNU environment
to the LD_LIBRARY_PATH of the webserver I must wrap the cgi in a 
shell-script ('wrapserv') doing just that.

If I call this with an IMG-tag  ('<img 
src="/cgi-bin/wrapserv?map=/somedir/mapserver/htdocs/relief.map&mode=map">') 
I actuallly get inline maps in the doc - surprisingly enough. But this is 
actually meant to be an interactive site.

To check the problem with the TEMPLATE file, which is globally defined 
under the WEB-object, I deleted all layer definitions without CLASSes as Steve 
said. No avail. The problem does not seem to be closely related to the CGI 
but to the SunONE server, I guess, because if I insert an empty '[ ]' with 
none of the CGI-keywords anywhere in the template the effect is just the 
same:  
Head of the template file :

Segmentation Fault

This is strange to me, but (this) SunONE seems to intercept and abort  exactly 
where it finds an angular bracket.
