Your log file shows:

Assertion failed: (isa<X>(Val) && "cast<Ty>() argument of incompatible type!"), function cast, file /usr/src/contrib/llvm/include/llvm/Support/Casting.h, line 255.

which would lead to "c++: error: unable to execute
command: Abort trap (core dumped)". So: not like an
inability to establish enough free RAM after some
number of tries.

It is likely someone would want to see the backtrace
from looking at a core dump, although you may not
have debug symbols in place in the compiler. Hopefully
the .sh and .cpp for instance-Klass will allow
reproduction of the assert.
