I installed Ubuntu 14.04 (linux header 3.16.0-30-generic) in VirtualBox VM on the 11th of April 2015.
Installed omnisharp-vim and followed installation instructions. Everything was working.
The following day Ubuntu prompted a system upgrade for the newer linux kernel 3.16.0-34-generic.
All other packages including mono is up-to-date.
However when starting OmniSharp.exe I now get the following error:

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

I believe there is a race condition somewhere as it might work 1 out of 10 attempts. The stacktrace is also different when it fails but this one is the most detailed. Sometimes the stacktrace may even be empty (it probably fails too early?).
Note that in all cases it fails before it finishes parsing/loading the solution.
Fortunately I can use GRUB2 to boot with the previous kernel (3.16.0-30-generic) with which I cannot reproduce this issue.
