with 2.5.1 dwarf should be fine for 64 bit (though my tests with 64
bit are rather sporadic)<br>

if you have specific problems please report<br>

yes, but only for a few things.<br>
<br>
Before changing it, ensure your gdb can deal with it.
Normally that is the cases<br>
- On Mac, not sure as apple still distributes 6.3.50<br>
- win 64 before fpc 2.6 , dwarf may not work<br>
<br>
when choosing dwarf, always use "+ sets" (unless maybe again
your gdb is real old, I have used it with gdb 6.7.5 all ok)<br>
<br>
dwarf 3 is experimental and works LESS well than dwarf (2)
=> unless you have a specially patched gdb (archer
branch). <br>
(Though I did not test the archer gdb, no idea, if it is
good)<br>
<br>
<br>
----------------<br>
biggest diff is<br>
<br>
with dwarf you can inspect certain properties. that is ONLY
properties that directly map to a field.<br>
Neither stabs, nor any dwarf will call a getter function.<br>
<br>
stabs deals better with<br>
- nested (dynamic) array<br>
- param-by-ref "function foo( var RefParam: TBar)"<br>
<br>
however Laz 0.9.31 deals with most of this.<br>
<br>
there may be a few other diffs. I have no complete list<br>
<br>
some fpc (or maybe the linker) had bugs, leaving out line
info for parts of try except. But I do not recall the exact
details<br>
