Andrew,
Now that we have a set of patches to fix the breakage in current gcc
trunk to dsymutil, I have uploaded a much more complete walk under x86_64-apple-darwin10.
I haven't managed to walk into _Unwind_Exception() yet but I do see that the
crash occurs on continuing from the 39th instance of the _Unwind_Exception() breakpoint.
Is there some way I can get the unwinder data from inside of libgcj itself before
the call to _Unwind_Exception()? If the bad unwind information is being generated in
libjava wouldn't it be just as easy to see that from outside of libgcc (before the call
to _Unwind_Exception()?
Jack
