<div>
<pre>findNeededSubprograms in IRMover.cpp assumes that the CU->getSubprograms() is
not null and dereferences it, but it is null sometimes in my experience. This
probably happens when the compile unit has no subprograms.
Inserting:
if (!CU->getSubprograms()) continue;
just before the IRMover.cpp line 1196 fixes it for me</pre>
