test msan #564

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
compile and test run with msan=1 

set all these: GYP_DEFINES="msan=1 msan_track_origins=2 
use_prebuilt_instrumented_libraries=1"

fix any issues.
document how to do it in Getting Started.

To get the instrumented libraries binary package downloaded, you need the 
GYP_DEFINES set in the environment.
To make sure you trigger a new Chromium sync when you have that, do like this:

export GYP_DEFINES="msan=1 msan_track_origins=2 
use_prebuilt_instrumented_libraries=1"
rm chromium/.last_sync_chromium 
gclient sync

I landed https://codereview.chromium.org/1665573003/ that allows compile to 
work.

Then I get this error:
