Build oxygen cros build for mus.
Ran chrome --mash

After startup was complete I closed the window using the linux window control.

I receive this stack trace:

/Work/src/out/oxygen/../../build/linux/ubuntu_precise_amd64-sysroot/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../include/c++/4.313:
    error: attempt to subscript container with out-of-bounds index 0, but     
    container only holds 0 elements.
