JVM crashes with SIGSEGV when selecting a variant column

[MGathier]

We are using DuckDB with the Ducklake extension from a Java program. If we select a row that contains a VARIANT column, the JVM crashes.
The failure occurs with some values in the VARIANT column, not for all rows.

I have attached the hs_err file.

sample_hs_err..log

Thanks for the report! I can reproduce this, will take a look.

In current version the workaround is to cast the VARIANT column to the expected type that is going to be used from Java:

SELECT globalSequence, data::VARCHAR AS data FROM events

Just FYI, this should be fixed by #694, it is going to be included into the upcoming 1.5.4 update.
