Of course.
Thx for report and patch.
However I will contact the original author of the simmetrics library
https://github.com/jokillsya/libsimmetrics
to report him this error and the patch.

Thank you very much for all feedback! the last example crashed also so I
have tried with try and error to trace it down into the library and it
looks like the problem are this 2 lines in file
src/libsimmetrics/simmetrics/tokenizer.c
tmp = calloc((init_len + qtype->qgram_len),

Then that's the one to use for debugging. It is extremely simple and contains
no database access at all so now you know the problem has
Hi Milan,
thx for your patch.
SQLITE_STATIC --> SQLITE_TRANSIENT
I try to apply it for testing:
but seem nothing change .
However I leave it in the code to allow you to test.
I submit also a new dll.

So I was able to identify the record doing the problem. I have tried to
find what is so special on that record and it is size 20 characters.
When I have this 3 examples with last name lenght 19, 20 and 21
characters only the size 20 crash.
.load ./libstringmetrics.so
select a.firstname,

Your SQL pass, so it is somewhere in the library. The problem is how to
find in the big data where exactly. I am now going one character by each
other, because it is probably only one specific record kind doing that.
I was able to compile the library under linux and running strace looks
like

Dear Andrea,
I am also facing problem with sqlite closed by windows because of crash.
On same data this query crash:
select load_extension("libstringmetrics.dll");
select a.vorname, b.vorname, a.nachname, b.nachname,
stringmetrics("qgrams_distance","similarity",a.nachname, b.nachname, "")
Dear Andrea,
thank you for the answer. The only idea I have so far is the line 452 in
file wrapper_functions.c
sqlite3_result_text(context, metrics, strlen(metrics)+1, SQLITE_STATIC);
I would change that to
sqlite3_result_text(context, metrics, strlen(metrics)+1,
SQLITE_TRANSIENT);
but I don't
Hi Milan,
thx for your report.
I try to see a check, and effectively I notice the problem is in the
qgrams_distance when used the metrics option.
As reported in the readme, the stringmetrics extension is based on the
https://github.com/jokillsya/libsimmetrics
library.
The code on the metrics
Dear all,
I have some problems with https://github.com/aperi2007/libstringmetrics
. For example:
When I use "similarity" in qgrams_distance, I get good results. But when
I use "metric", it works only if it is only once in the query. When
there are 2 different usages, they somehow interfere
