--- Comment #2 from François Gouget fgouget@codeweavers.com 2012-10-31 05:51:19 CDT --- I ran the CCleaner installer with and without warn+heap but I could not reproduce the crash and did not get heap errors. Could you add the following trace at the start of CommandLineToArgvW():
TRACE("(%s, %p)\n", debugstr_w(lpCmdline), numargs);
And run the installer with +shell. That will tell us what the command line CommandLineToArgvW() parses is and thus why it may get it wrong. (Alternatively you could run it with +relay and fish that information out of the large log).
