Title: segfault in todo plugin
Post by: grv575 on September 23, 2005, 11:19:29 pm
Crash on latest CVS with wxWidgets 2.6.2 ansi windows.  I get a messagebox error Project X doesn't exist (which is normal) and then a segfault.  Offending line is:

plugins\todo\todolistview.cpp:71
Code
void ToDoListView::LoadUsers()
{
	wxString oldStr = m_pUser->GetStringSelection();

Either the user pointer is null (I have no users for some todo items) or there is no current selection in the todo listview i guess.

Code

Note that this is latest CVS compiled against wx 2.6.2.  Using the 2.6.2 dll I get the crash, but if I just drop in the 2.6.1 dll (apparently it's still backwards compatible), then there's no crash.  So maybe one of the bugs they fixed with strings or so :\

The above crash goes away if I turn off the autorefresh todo list setting.

So it loads with that off.
However, even with that setting off I get a crash on exit (closing CB), again in the todolist listview.  These backtraces are all against the 2.6.2 dll.

Just wanted to report that this is fixed with latest cvs (built from sources yesterday).  There is still the crash on exit if you try to exit before codeblocks finishes loading.  Looks like something to do with the threading cleanup code.  Maybe thread cancellation should release any acquired mutexes as well as other resource cleanups?
