I realize that I am replying to a question that is well over the one-
year-old mark (the question that appears below about a gdb crash with
the output: macrotab.c: internal-error: macro_bcache_free: Assertion
`! t->bcache' failed).
I experienced this same error for the first time today, using a newer
version of Xcode and a newer version of gdb.
What wound up fixing things for me turned out to be a simple act: I
simply deleted all my breakpoints from Xcode. I opened the Xcode
breakpoints window using the shortcut command-option-B, then I
selected all of them and deleted them.
Now I am able to debug in Xcode again.

Here is my version info:
Xcode 3.1.3
GNU gdb 6.3.50-20050815 (Apple version gdb-966) (Tue Mar 10 02:43:13
UTC 2009)
