[cfe-dev] Clang error

[Gonsolo]

With clang version 97437 and llvm 97442 built in Release mode I get the 
following error:

Stack dump:

clang: error: compiler command failed due to signal 11 (use -v to see 
invocation)

when compiling the following file:

#include <boost/shared_ptr.hpp>
using ::boost::shared_ptr;

class A {};

int main()
{
	shared_ptr<A> a;
}

Debug mode seems to work.

Reduced testcase:

inline int atomic_exchange_and_add( int * pw, int dv )
{
     int r;

     __asm__ __volatile__
     (
         "lock\n\t"
         "xadd %1, %0":
         "=m"( *pw ), "=r"( r ):
         "m"( *pw ), "1"( dv ):
         "memory", "cc"
     );

     return r;
}

void release() {
	int use_count_;
         if( atomic_exchange_and_add( &use_count_, -1 ) == 1 ) { }
}
