New Revision: 116917
URL: http://llvm.org/viewvc/llvm-project?rev=116917&view=rev
Log:
GCC 4.4 warns that Receiver may be used uninitialized in this function.
As far as I can see, gcc is right to think this! The following change
will cause a nice segfault rather than undefined behaviour if this case
occurs. Someone who understands what this code is supposed to do should
probably take a proper look.
