New issue 7394 by erik...@chromium.org: UMR in unit_tests.exe -
PluginRequestInterceptor::MaybeIntercept (WriteFile)
http://code.google.com/p/chromium/issues/detail?id=7394
Unfortunately, I can't pin down exactly when this happened because purify
was crashing/hanging near when the error started. It first appeared
in build 1910:
http://build.chromium.org/buildbot/waterfall/builders/XP%20Unit%20(purify)/builds/1910
but could have shown up in either of the previous two builds as well:
http://build.chromium.org/buildbot/waterfall/builders/XP%20Unit%20(purify)/builds/1909
http://build.chromium.org/buildbot/waterfall/builders/XP%20Unit%20(purify)/builds/1908
From my quick look, none of the checkins really stands out as a likely
cause.
