Joel,
   Is anyone working on fixing gdb to be compatible with the new -pie linker default
on darwin11 (Lion)? Currently FSF gdb 7.3.1 can only debug binaries linked with -Wl,-no_pie.
The default -pie linkage on Lion prevents breakpoints from being found in gdb.
           Jack
ps Of course Apple's own forked gdb is patched to handle this -pie linkage change.
