[Lazarus] Mac App bundle question

[Martin]

Since I am not an expert, a quick question regarding app bundles:

It is always mentioned that without, any app will behave less than 
pleasant...

I understand (or I believe I do) that if you start an app (from the 
desktop) you click the bundle.

But if an app is started from a shell, then it seems one can start the 
executable inside the bundle?
   ./lazarus.app/Content/MacOs/lazarus
Will that run a misbehaving app, since it refers to the exe, and maybe 
not the bundle, or will the bundle be used?


I am asking, because if the above tick does start the app normally (as 
if the bundle was started), then it could be checked if the macports gdb 
is usable for development.
Since some people reported problems using the gdb supplied by apple 
(mostly people with intel 64 bit, debugging 32 bit carbon app)

I do not yet know if the macports gdb is any good.
But previous tests showed that unlike the apple supplied one, it fails 
to start the app, if it is given the name of the bundle
   apple-gdb  ./lazarus-app   => works
   macports-gdb  ./lazarus-app   => fails

but maybe
   macports-gdb   ./lazarus.app/Content/MacOs/lazarus
can be used?
