New issue 20653 by d...@chromium.org: Invalid read in unixWrite and sqlite3MemSize in history::HistoryBackend::Init() on mac http://code.google.com/p/chromium/issues/detail?id=20653 This was originally the second part of bug 11282 but that was getting messy, so I'm breaking it out into its own bug report.

http://www.sqlite.org/cvstrac/tktview?tn=694 dismisses a warning similar to the first one without any discussion. I guess I'll file a new bug against sqlite for the pair, since the two warnings seem to always occur together. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
