Comment #1 on issue 24846 by [email protected]: Crash: Data schema link
with Alt + click
http://code.google.com/p/chromium/issues/detail?id=24846
Confirmed with ToT (r29095). What I did to reproduce the bus is as follows:
1. visit the http://ss-o.net/test/chrome_alt_click.html
2. hover the mouse pointer over the blue "a" character. Note that the URL
scheme of the link is 'data':
<a href="data:text/plain,a">a</a>
3. press Alt, then left click the link.
The reason of the crash is a CHECK failure:
[12236:8624:1014633700:FATAL:resource_dispatcher_host.cc(734)] Check
failed: false.
chrome.exe has triggered a breakpoint
bool known_proto = URLRequest::IsHandledURL(url);
if (!known_proto) {
CHECK(false);
}
Here is the backtrace:

This issue seems not to be reproducible on Linux. Probably Windows specific
bug? I've changed the OS label to OS-Windows.
