            Bug ID: 15637
           Summary: Regression: Assertion failed: ((!TParams ||
                    DbgNode->getNumOperands() == 14) && "If you're setting
                    the template parameters this should include a slot "
                    "for that!"), function setTypeArray, file
                    DebugInfo.cpp, line 623.

This is reduced from code in WebKit:

thakis$ cat repro.ii
template <typename T> union Value { int a; };
void g(float value) {
  Value<float> tempValue;
}

thakis$ ~/src/llvm-svn/Release+Asserts/bin/clang -cc1 -triple
i386-apple-macosx10.6.0 -emit-obj -g   -x c++ repro.ii 
Assertion failed: ((!TParams || DbgNode->getNumOperands() == 14) && "If you're
setting the template parameters this should include a slot " "for that!"),
function setTypeArray, file DebugInfo.cpp, line 623.

This is at r178474 (which was current trunk when I started delta an hour or so
ago). Doesn't happen at r178178.
