Segmentation faults are potentially very serious bugs in Aspectator and thus should be fixed quickly.

Status changed from Open to Resolved

The reason of this segfault was in that Aspectator doesn't support GCC vector type, but just use NULL instead of this type. At some point this NULL was dereferenced. From commit df9bb68 of the bug-4395 branch in Aspectator submodule Aspectator fails if it encounters unsupported type.
