<pre>clang fails to compile function with __unaligned argument to class member:
=============== nice.cpp ==============
class A;
void func(void (A::*a)(int) __unaligned);
=======================================
<span class="quote">>>> clang -v</span >
clang version 7.0.0 (trunk 326880)
Target: x86_64-unknown-linux-gnu
Thread model: posix
...
<span class="quote">>>> clang++ -c nice.cpp -fms-extensions</span >
nice.cpp:2:6: error: variable has incomplete type 'void'
void func(void (A::*a)(int) __unaligned);
^
nice.cpp:2:20: error: expected unqualified-id
void func(void (A::*a)(int) __unaligned);
^
nice.cpp:2:21: error: use of undeclared identifier 'a'
void func(void (A::*a)(int) __unaligned);
^
nice.cpp:2:27: error: expected '(' for function-style cast or type construction
void func(void (A::*a)(int) __unaligned);
But this test is compiled without any errors using cl and icl -
