Question

Hello，
When I use Adaptivity and set 'block' in Indicators, I get the following error:

Segmentation fault (core dumped)

This error does not occur when 'block' is not used. What causes this? Is there a way to solve this problem? My input file is as follows:

Hello

If you use a comboMarker that is not block restricted, and use the block-restricted one inside the combo and a "do-nothing" for the other blocks, does it work?

For now the solution is to remove block

Either way i ll investigate this next week to remove the seg fault
