Hi,

I am using version 0.9.20 on Linux (Ubuntu derivates, uname see [1], [2]).

Version 0.9.20 was never officially released. The release was withdrawn due to a corruption bug. I suggest you downgrade to 0.9.19.

Hi,

after hitting a known problem with 0.9.18, I went to the Git repository to fetch the latest release I found there -- this is why I took 0.9.20.

I have repeated my test with 0.9.19, but unfortunately, the very same error occurred...

I am going to try to write a small C program to see whether I can reproduce the behaviour.

Regards,

Klaus

Hi,

I am now able to reproduce the problem with a sample program. I guess that the problem is somewhat deeper and not necessarily directly related to mdb_cursor_del as it seems to depend on the order the data is inserted into the database. If I do this in a pre-ordered way, the problem does not occur, but if I shuffle the data, it does. I also tried a smaller number of records, but then the problem disappears also.

I have attached the test program to this e-mail. I hope it does not get filtered out.

Regards,

Klaus
