Hi,
I also encounter this issue and I think your fix will not work.
While it fixes compilation, it introduce a latent bug as now the structure definition in asan no longer match the one readdir expects.
When compiling for 10.6 and later, OS X implicitly replace call to readdir (and other functions) by readdir$INODE64 call which properly handle the 64bit structure, but call to readdir will always use the old structure.
So if using 64 bit version of the dirent struct, ASAN should interpose readdir$INODE64 and not readdir symbol.
