Where should I be looking to trace down this bus error?

[Robert Backhaus]

I am currently getting a buss error on startup. Sorry I can't get you
a better backtrace, but building chromium with debug enabled is broken
for me.

Any advice where I should look to fix this? I have just finished a
portmaster -f chromium.
