THIS COMMENT ALSO ADDED TO (PARENT) BUG
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1699772
However, that bug has FixReleased (at least for 64-bit JVMs). I guess it
should be also fixed for 32-bit JVMs launched from C on 64-bit kernel.
I'm not sure, whether it would be better adding this comment just to Bug
1699772, or just to this ("duplicate") Bug 1700270, or creating just another
bug ID.
I have chosen adding it to Bug 1699772 and also here, since my code example is
based on previously-provided test.c which I downloaded from Bug 1700270.

Hi,
problem still present on linux-image-4.8.0-58-generic with these conditions:
- while executing JVM launched from >>32-bit<< C (on 64-bit kernel)
- defining "higher" JVM stack size (eg. -Xss2048k JVM argument)
=> causes JVM segmentation fault
Attached test case (sources + binary + output logs):
Bug1699772_i386_jvm_segfault_problem.tgz
test_case1.c (32-bit) => using -Xss1024k => RUNS OK.
test_case2.c (32-bit) => using -Xss2048k => Segmentation fault.
test_case1.c (64-bit) => using -Xss1024k => RUNS OK.
test_case2.c (64-bit) => using -Xss2048k => RUNS OK.
