Hi,

I use the source from the Xdebug 2.1.0beta1 package which I found here [1]. After compiling XDebug the local vars are shown (and are not uninitialized) but Apache crashs.

Looks like my fix for the threaded Apache broke it for the normal one. I'll have a look.

Please try the latest SVN version, this is most likely fixed now.

No more crashes. Thanks!
But now I get another issue. When I continue after my breakpoint netbeans starts spewing out socket exception dialogs and I have to force kill it. Any ideas? This didn't happen with my old snapshot (middle of oct). Should I open a new issue for this? How can I debug this? Do you need an xdebug remote log?

Cool, thanks for testing. And yes, please open a new issue with a remote log attached!
