One quick thing to do would be to take OGR out of the mix. Just set up a
mapfile with the feature in question as a WKT inline feature. Something like:
LAYER
NAME 'badwkt'
TYPE LINE
STATUS DEFAULT
FEATURE
WKT ' MULTILINESTRING ((-110.220980 38.982832, -110.220887 38.982863,
-110.221614 38.982708, -110.220980 38.982832),(-110.220980 38.982832,
-110.220887 38.982863, -110.221614 38.982708, -110.220980 38.982832))'
END
CLASS
STYLE COLOR 0 0 0 END
END
END
Then try to draw... If this fails then it's a MapServer issue.

Steve,
Version 6.4.1 built on the same machine with the same settings does not have
the issue.

Steve,
We will add some debug to the OGR read later today or tomorrow.
How do I turn on the maximum debug?
Thanks

How are you submitting the WKT to MapServer? Is it via MapScript, via inline
features or some other mechanism?

Devs,
The MULTILINE string below gives the following in mapprimitive.c and then as
the first shape has 0 points the msSmallMalloc fails as the size passed to it
is -8.
[Wed Aug 13 07:55:10 2014].618971 Shape contains 2 parts.
[Wed Aug 13 07:55:10 2014].618987 Part 0 contains 0 points.
[Wed Aug 13 07:55:10 2014].619001 Part 1 contains 3 points.
[Wed Aug 13 07:55:10 2014].619016 0: (882.383078, 511.333078)
[Wed Aug 13 07:55:10 2014].619032 1: (825.909890, 260.048026)
[Wed Aug 13 07:55:10 2014].619049 2: (882.383078, 511.333078)
Any clues what we should look at next?
This same source data file and layer work with older versions of mapserver 6.
Thanks

Folks,
With Mapserver 6.5-dev from git and GDAL 1.9.1 the line below either does not
draw or causes mapserv to error and not render an image without an error
message.
MULTILINESTRING ((-110.220980 38.982832, -110.220887 38.982863, -110.221614
38.982708, -110.220980 38.982832),(-110.220980 38.982832, -110.220887
38.982863, -110.221614 38.982708, -110.220980 38.982832))
Changing the final digit on either of the first or last lats/longs and it draws
ok!
Any ideas?
Thanks
Ian
