<pre>Hi Richard,
I pulled 8c98c8803430804010da06a07cfb291dab59067c, but got parse bug again. My
guess is that you fixed the non-template version of friend-noexcept
specification. It looks like the template version is still not working,
considering this example:
class Foo {
template <typename X>
friend void test(X, int = 0) noexcept(true) {}
};
I got similar dumps like:
PLEASE submit a bug report to and include the crash backtrace, preprocessed
source, and associated run script.
Stack dump:
....
I think you might want to add template-friend-noexcept test case for this:
diff --git a/clang/test/Parser/cxx0x-decl.cpp
b/clang/test/Parser/cxx0x-decl.cpp
index 4ddcb8ccfd..8be98d6ef2 100644
