I reported it here

I found that reverting
https://svn.freepascal.org/cgi-bin/viewvc.cgi?view=revision&revision=43245
(in fact I just took sdfdata.pp from 3.0.4)
fixes the segfault.
Michael, what do you think?
Seems like a bug somewhere. I'll need to look at it. Probably has something
to do with the default codepage: Lazarus changes that.
What worries me is the fact that it is so easy to mess up the heap. What
other dragons are lurking ahead in 3.2.0?
Looking at the bugtracker, there could be several.
I think we may need to release a 3.2.2 after a relatively short amount of time.
For the record, I tried to set the codepage of the component to 'utf-8' and
it still segfaults, so I don't think it's because of the default codepage.
We'll see.
This is the only relevant change in the component, so that is the most likely candidate.
What is more puzzling is that it only happens in Lazarus.
Also the fact that some of the TFieldDefs.Add are procedure and some
functions doesn't seem right.
They are simply overloaded versions, but all boil down to the same.
Some of these exist for Delphi compatibility. I doubt this is the cause.
Michael.
