Severity: normal

Dear Maintainer,

lz4-java tests are failing consistently (well, twice so far on the
buildds) with a JVM segfault, on the i386 arch only.  I am not able to
reproduce when cross-building on amd64 with --arch=i386 in a sbuild
chroot, so I can't provide the error report or compiler replay data
(yet), but the failure message is:

# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0xf758ddce, pid=634517, tid=634556

The buildd logs are available here [1,2]; both fail with:

# V  [libjvm.so+0x880dce]  PhaseIdealLoop::build_loop_late_post_work(Node*, 
bool)+0x14e

I will try to reproduce with QEMU.

Thank you,
