[Lazarus] debugger crashing on OS X

[dmitry boyarintsev]

Hello John,

The problem with OSX debugger is that Apple has its own gdb-fork (a
bit different to GNU gdb). To makes things worse, gdb slightly changes
from one Xcode minor release to another. So, if you want to have your
debugger working with Xcode 3.2.2. please send the content of Debug
Output window, if possible.

> Do any of the Mac devs have Snow Leopard 10.6.3 and XCode 3.2.2?
I guess, we don't have such information, though there have been some
issues in the past with 10.6 and Xcode 3.2 debugger.

> Is gdb running in 64-bit mode the source of the debugging problems?
Yes. That's what Xcode does.

> If so, is it possible to compile Lazarus as a 64-bit application on OS X?
No. Lazarus is Carbon (32-bit only) based, and Cocoa widgetset (that
supports 64-bit) is not ready yet. However even 32-bit Lazarus is able
to debug 64-bit applications, because it uses gdb as stand-alone
process.

thanks,
Dmitry
