Subject: [BUG]: libffi 3.3 breaks OpenJDK Zero on 32-bit PowerPC
Date: Fri, 14 Feb 2020 11:14:00 -0000	[thread overview]
Message-ID: <9b5d9318-5ef1-593d-daab-3428818707b5@physik.fu-berlin.de> (raw)

Hello!

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:

Thread 2 "java" received signal SIGSEGV, Segmentation fault.
