I've built the DRLVM on Linux for the following cases:
1. w/o patches listed above;
2. w/ H-898 patch;
3. w/ H-898 & H-853 patches.
'Segmentation fault' occurs for all cases, unfortunately.
I was able to run most of smoke tests on Linux a few days ago, but now
I'm having the same segfault failure.
Some observations are:
- In the interpreted mode (-Xint option) it reports ClassNotFoundException, so
it seems VM can no longer load the classes from jars on Linux. I was able to run
a single "Hello" class though.
- Segfault actually happens during VM shutdown, after the main() is
already completed with CNFE error. I wasn't able to find the exact
point of segfault though - it seems it happens somewhere in a jitted
code, gdb doesn't show a much of useful info in that case:

Previous frame inner to this frame (corrupt stack?)
I'm continuing investigation, the same behavior is observed on Linux
if run with classlib's launcher.
Thanks,
Andrey.
Thanks,
