Sorry, I don't have the wherewithal to get more info but I have repeated
this now on 4 different machines (debian jessie/stretch; centos).

I did notice that sometimes those two offending lines
"
   drop variable varschema2.testv cascade;
   create variable if not exists testv as text;
"
have to be repeated a few times (never more than 4 or 5 times) before
the crash occurs (signal 11: Segmentation fault).

Should be fixed now.

Thank you for report

Pavel
