warning: enclosing function for address 0x124cf0bf0
This warning occurs if you are debugging a function
without any symbols
(for example, in a stripped executable).  In that
case, you may wish to
increase the size of the search with the `set
heuristic-fence-post' command.

Otherwise, you told GDB there was a function where
there isn't one, or
(more likely) you have encountered a bug in GDB.
Current language:  auto; currently asm

i believe their is some bug associated with memcpy on
64-bit architecture as well in egcs-1.1.2 and also the
last release of gcc.
