This is strange.

This kind of error message generally means that you have attempted
to load a BEAM into an older run-time system than it was compiled
for.

Opcode 153 is the new 'line' instruction introduced in the R15 release
(to support line numbers in exceptions), but R15 has not been released
yet. The support for line numbers in exception is included in the 'master'
branch in our git repository, though. Did you happen to build any BEAM
files with a BEAM compiler compiled from the master branch?
