Comment #4 on issue 16274 by [email protected]: Crash -
SdchManager::GetVcdiffDictionary(std::basic_string<char,std::char_traits<char>,std::allocator<char>
> const &,GURL const &,SdchManager::Dictionary * *)
http://code.google.com/p/chromium/issues/detail?id=16274
This browser crash bug is caused by the current mistaken implementation of
the
experiment to determine the impact of SDCH (vs non-support of SDCH) on
global
rendering time. The primary cause is that I (mistakenly) disabled SDCH by
not
initializing the SDCH module, when the correct approach is to simulate the
command
line flag for disabling SDCH.
I have a CL that corrects the error. The error is restricted to the
changes to
browser_main.cc, in/around the initialization code for SDCH.
The impact of this bug is significant. If a user has SDCH content in a tab
at
startup, then with 50% probablitiy, the attempt to decompress that cached
content
will induce a browser crash. (The current experiment disables SDCH with
probability
of 50%).
