This is turning out to be something of a heisenbug: I'm having problems reproducing this on my machines at work, even though I've done so before. I'm going to try and see if I can get it again on my home machine, where I originally discovered the problem, this evening. Can re-open this once we've figured out to reproduce it. |
Building mozilla from CVS (using egcs-1.12-12), I've been trying to set breakpoints and inspect code in a certain function. Specifically, I'm trying to play with mozilla's nsEventStateManager::CheckForAndDispatchClick in mozilla/layout/events/nsEventStateManager.cpp. If I do "list nsEventStateManager::CheckForAndDispatchClick" from gdb-4.18-4, I see the following (incorrect) output: 477 } 478 } 479 } 480 } 481 return ret; 482 } 483 484 NS_IMETHODIMP 485 nsEventStateManager::SetPresContext(nsIPresContext* aPresContext) 486 { If I revert back to gdb-4.17.0.11-6 (as shipped with RH6), that same command produces the following (correct) output: 816 817 NS_IMETHODIMP 818 nsEventStateManager::CheckForAndDispatchClick(nsIPresContext& aPresContext, 819 nsMouseEvent *aEvent, 820 nsEventStatus& aStatus) 821 { 822 nsresult ret = NS_OK; 823 nsMouseEvent event; 824 nsCOMPtr<nsIContent> mouseContent; 825 PRBool fireClick = PR_FALSE; If you want help building mozilla or otherwise reproducing this, I can usually be found on irc.mozilla.org in #mozilla.
