I've came to same solution by compiling the artifacts myself, but it seems to me to be inconsistent with the character of the exception (instruction that pc is pointing to is not accessing memory, but the abort was caused by NULL dereference). I suspect there was some difference between binary on CI and the one I compiled myself.

I compare md5sum of stripped binary and it's same
