if dynamorio base conflicts w/ app or before-DR library base => fatal reachability problem

From bruen...@google.com on December 02, 2011 14:24:58

pasting from a problem raised over email:

Most likely firefox has a library that it loads at or overlapping the DR lib preferred base of 0x0000000071000000.

As a workaround you can reconfigure with something like this (adjust the value to avoid firefox libs, but keep it in the lower 2GB):

cmake -Dpreferred_base=0x61000000 .

And then rebuild.

Long-term we will have DR loaded by our loader (right now the client and its libs are but not DR) and this problem will go away. It was never high enough priority to tackle in the past: this is the first we've heard of a conflict.
