ucFiber.cpp
the attached code was compiled with libc++
clang++ -c ucFiber.cpp -std=c++0x -U__STRICT_ANSI__ -stdlib=libc++
It used to compile an run with previous revisions.
The revision that resulted in this error must be between Jul 5 and Jul 10.
clang++ -c ucFiber.cpp -std=c++0x -U__STRICT_ANSI__ -stdlib=libc++
Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i) ==
Params[i]->getType()) && "Calling a function with a bad signature!"), function
init, file Instructions.cpp, line 191.
