I have a Mach-O program that uses GetDiskFragment to load Carbon CFM
shared libraries and call functions in them. This all worked perfectly
in Panther and OS X versions before that. But in Tiger, GetDiskFragment
is actually throwing an exception when I attempt to load one of these
libraries. No error return - an exception jump entirely out of the function.

Is GetDiskFragment() supposed to work? Or is there a more appropriate
function I should be using to load old-fashioned Carbon shared libs?

I see this note:

But I wouldn't expect that generates an exception. Make a degenerate
example project that reproduces the failure and report to Apple.
