Can be anything - most probably an "out of memory".
Please provide enough information to reproduce the bug.

Most probably out of memory. Notwithstanding my desktop of 64 GB RAM, my calculations are very complex. Thank you for your attention. Best regards.

Without any information about the Singular version (etc.),
it can also be a 32bit-version, meaning that not more than ca. 3GB can be allocated.

===============

This means that my desktop is capable of 64 bit. So, are things working as I thought? Thank you very much.
