Hi All,
We are having a problem with the cgi mapserv executable.
Some symptoms are
* when calling with a valid query string, a png is returned as expected
* when there is an error in the mapfile, nothing is returned.
response headers show "Content-Type: text/xml;" but there is no xml
response data.
* running mapserv on the command line with the same query string
returns the expected output.
* running mapserv -v on the command line returns "double free or
corruption (out) Aborted (core dumped)"
gisusr@osagisdevl:~$ mapserv -v
MapServer version 7.4.3 OUTPUT=PNG OUTPUT=JPEG OUTPUT=KML SUPPORTS=PROJ
SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO SUPPORTS=ICONV
SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT
SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER
SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS SUPPORTS=GEOS
SUPPORTS=POINT_Z_M SUPPORTS=PBF INPUT=JPEG INPUT=POSTGIS INPUT=OGR
INPUT=GDAL INPUT=SHAPEFILE
double free or corruption (out)
Aborted (core dumped)
gisusr@osagisdevl:~$
This is on a compiled version of mapserver on RHEL8. The same result
with mapserver 7.6.2.
Does anyone have suggestions on how to track this problem down?
