Re: [basex-talk] Improper use? Potential bug?

Hi Rob,

Our functional mastermind Leo has fixed a bug that may also fix your runtime exception [1]. Your feedback on the latest snapshot is welcome [2]. If the problem persists, you could set INLINELIMIT to 0 and report back to us what happens.

Cheers, and a big thank you to Leo, Christian

Hi Christian,

I encountered this error-message.

I have a strong feeling that this error is related to previous reports, see

· my email dd 13-05-2013 and 03-12-2014

My program is heavily recursive so it is hard to create a running snippet but I will try.

Hopefully in the mean time you can have a look at the error.

TIA,

Rob Stapper
