After libffi was upgraded to 3.3 in Debian, all OpenJDK versions started
to break on 32-bit PowerPC with the freshly compiled JVM crashing with
the following backtrace:
Thanks for pointing this out. I only figured out how to do CI testing for 32-bit PowerPC after the 3.3 release, and there are indeed a number of failures:
travis-ci testing is done with a powerpc-eabisim GNU toolchain. We need to start going through these failures assuming that powerpc-eabisim is a close approximation of the system you are using.
