Is CC crash, or Debugger plugin?

Pressing ctrl+shift+. is very deadlocky operation, it happened twice already today. Latest version of debugger's branch.

Try to disable the Symbols Browser.

oBFusCATed · August 23, 2011, 03:50:31 PM

OK, but I'm not using the symbol browser at all.

oBFusCATed · August 23, 2011, 04:11:55 PM

Disabled the symbols browser and got a crash instead of deadlock. Somewhere in AddToken().

Edit: And a deadlock switching to one just opened file...

Here is the backtrace from the newly-opened-file-deadlock:

Especially on linux.

BTW:
The CCLockerTrack class is useless, because when you get a dead lock, you cannot inspect the debug log.
Or do I miss something?

You'll need to use the C::B command line option to log to a file in that case.

oBFusCATed · August 24, 2011, 02:54:40 PM

OK, I've just replaced the logging with a simple printf, simple but effective

The crashes still exist?
The original crash is 99% fixed. C::B has not crashed for the last couple of days.
Unfortunately it crashed again
Same backtrace... and again it has happened, when I was hovering with the mouse over a variable

Try rev7419?

oBFusCATed · August 26, 2011, 12:23:44 PM

After the next merge

The current debugger_branch revision is working relatively stable

killerbot: can you make a nightly build for trunk?

The current HEAD works well on Windows 7 or Linux Mint 11.
It's ready for next nightly build.

If only test from me, then, yes, It has been stable enough.
So, how do? :?
