Thanks for the report. You may be among the first to try the 2019 Intel
compilers, which are notorious/infamous for changing behavior at each
release.
You could try to comment out the #pragma command at line 833 of
nblist.c: it's not being used anyway in the standard compile.
It would be good to report this to Intel, as requested above: compilers
should not segfault, even when given bad code.
Or, just use gnu compilers (especially for cuda compiles).
...good luck...dac
