[Mapserver-users] junk pointer revisited

[Toomas Aas]

Hello!

I'm running Mapserver and PHP/Mapscript on FreeBSD 4.9. A couple of 
days ago I upgraded PHP from 4.3.4 to 4.3.6 and then I also re-compiled 
Mapserver using the newer PHP source tree. After that I'm seeing again 
mapserv dying with Signal 10 in /var/log/messages:

Apr 22 15:21:45 mail /kernel: pid 52647 (mapserv), uid 80: exited on signal 10

and this message in Apache's error_log:

mapserv in realloc(): warning: junk pointer, too high to make sense
[Thu Apr 22 15:21:45 2004] [error] [client 213.35.245.74] Premature end of script headers

I had exactly the same problem when I first installed Mapserver 4.0.1 
and back then I posted this message:

http://mapserver.gis.umn.edu/cgi-bin/wilma_hiliter/mapserver-users/0312/msg00100.html?line=3#hilite

Someone recommended me off-list that I shouldn't use both --with-tiff and
--with-gdal, so I recompiled without --with-tiff and the errors went away.
Now when compiling Mapserver again I made sure to not use --with-tiff but
still the error messages returned. Otherwise the ./configure line is exactly
the same (except that newer PHP source tree is used).

I also noticed that immediately *before* the "junk pointer" message in
Apache's error_log is this message:

wmftogif: not found
  Error: Can't open file (/home/mapserver/www/tmp/1082636396526241.jpg)

Might this indicate that this is all simply an error in our PHP/Mapscript
application? Can a "junk pointer" message be caused by wmftogif (whatever
that is) not finding a file it wants? Unfortunately I am not the one who
develops applications on this server, I just install the necessary base
software. So I don't know whether the error is caused by me or by application
developers.
