AH, I installed that version yesterday eve. I was only interested in the MI 
interface, so I didn't look closer. I was also surprised, since the docs 
(with 5.2 examples) didn't mention anything about supporting pascal.

Ah, those kind of files work (that are the ones I use for testing)

Since I attach to a proces (to avoid screen output to clutter the debug 
output) dynamic libs aren't loaded, resulting in a segfault most of the 
time (I haven't been succcesful to load the dynamic libs in gdb)
And since most Lazarus apps will have some GTK (and thus dynamic libs) in 
them, it won't be a workable solution.

I'm planning to base the debugger on the MI interface which seems do-able 
to me. In that case, I don't have to load  the libs manually and it should 
work more reliable. More updates on it soon.
