Finally found that this was because sqlite3 was in the uses list, so

I did my own dynamic loading with my own unit of another version/file of
sqlite. So probably there was a conflict with shared data. In my case it
looks like everything was ok if the linked library and loaded was the
same file (system libsqlite3.so). But if linked was system libsqlite3.so
and my loaded was a library with a different name/soname the faults took
place.
Just curious, such things occasionally can happen from time to time. Is
this about the way sqlite library is compiled so no two independent
copies of the library coexist dynamically linked/loaded due to
intersetion of the shared data. Or this is about the way linux handles
them?
It is best to ask this question in FPC devel mailing list, this behavior
may be a bug.
It is not a FPC bug; you're not supposed to use the 2 units at the same time.
There is no way the compiler can detect this. At best the linux linker
should detect it.
