The algorithms for figuring out whether you have stepped into another
function or out of the current function when we step out of the
address range of the source line you were stepping in were indeed
changed in gdb-477. Actually, we didn't do this, this was a change
from the FSF gdb, not that that matters much... They were made more
strongly dependent on our being able to figure out what happens in
the function prologue of the function that we've just stepped into.
I wouldn't be all that surprised if the Free Pascal Compiler
generates prologue patterns that gdb doesn't fully understand.
The sources to the gdb in Xcode 2.3 will show up shortly on:
http://www.opensource.apple.com/darwinsource/
It usually takes a week or so after the release for the tarball of
the sources to get posted.

Hello,
The gdb from XCode 2.3 can no longer step over any function calls
in programs compiled with the Free Pascal Compiler (it generates
stabs debug information). The gdb "next" command always results in
stepping into the called function (i.e., the result is the same as
if you'd say "step"). This problem does not occur with previous
gdb's on Mac OS X, with gdb's on other platforms, or with gcc-
compiled code and the current gdb on Mac OS X.
I've been comparing the stabs we generate with those from gcc,
manually edited some stabs in both gcc-generated code and in our
generated code, but have not been able to change the behaviour of
either (i.e., "break" the gcc stabs or "fix" ours).
Can anyone tell me what changed between gdb-437 and gdb-477 in this
respect? And if not, where I can download the source for gdb-477?
