Anyone have similar problems running their projects? I am using CThreads as the first unit in this project.

I tried using Lazarus on OSX a few weeks ago, and the debugger constantly crashed for me too, although in my case it was more like this: http://forum.lazarus.freepascal.org/index.php/topic,8991.0.html

Ok, I launched the app directly in the Project.app../Project from a terminal and that was able to report that a file I use for logging was not able to be opened for read/write (TFileStream). It was an exception raised on TFileStream.Create but GDB under Darwin could not pass that exception to me.

It wasn't a problem with Lazarus/FPC but rather with GDB under Darwin. It is advisable that ppl with GDB problems under Lazarus execute their apps from the prompt to get more specific debugging info during crashing. At least it helped for me.

But at least my app runs now.
