Bug#555928: wordnet: Memory crash in findtheinfo_ds() if using COORDS pointer searchtype

[Vikas N Kumar]

Package: wordnet
Version: 1:3.0-13
Severity: normal

There is a memory error in Wordnet 3.0 library when you perform the following 2
function calls with the arguments as shown:

SynsetPtr syn = findtheinfo_ds("agriculture", NOUN, COORDS, ALLSENSES);
free_syns(syn);

this will cause a crash (segmentation fault or coredump) at the end.

I have created a patch for it that cleans up all dangling pointers, and uses the
correct free_syns() calll instead of the free_synset() call at one location in
the findtheinfo_ds() function.

I am attaching the patch with this bug. (NOTE: I am using reportbug for the
first time, so if the patch does not get attached, I apologize. I will try
attaching it in response to this bug then.)

Thanks.
Vikas
