--- Quote from: thomas on June 25, 2007, 07:48:12 pm ---Steps to reproduce:
1. load Code::Blocks
2. click on codeblocks.cbp on the start here page to open it
3. wait a few seconds
4. close Code::Blocks
5. load Code::Blocks ---> access violation
6. load Code::Blocks ---> works fine
7. try (6) any number of times ---> works fine
8. try again from step (2) ---> access violation

Disable the CC plugin, and there is never any crash.

I've been using r4120 before, and never had any visible issues.

This has to be a windows issue or it was introduced after revision 4161 as I can't reproduce it here with revision 4161 on Linux.

rickg22:
Yes, it's a problem that appeared after 4164 or greater (no need to post "me neither", guys). It's either my code or Thomas'. Or perhaps a strange situation where both changes trigger the crash.

darthdespotism:
My Codeblocks (actual SVN) crashes on each startup /Ubuntu-Linux 7.04

Is this related to the discused bug?

rickg22:
It's most probable.

LoaderBase* seems to be the culprit, but having the source line numbers would be better.

Can you do us a favor? On your codeblocks directory, there should be a file called "codeblocks.RPT".
Open it with a text editor and browse to the latest entry. Can you copy and paste the lines here, please? Thanks! :)

dmoore:
i can't replicate at all with latest svn on win32. did you guys clear out your devel dir?

correction

copied output dir back to my main install location and reran cb: what do you know -- crash
