Description Pontus Astrom 2008-04-30 07:21:25 UTC 
The compiler exits with segmentation fault for this source file. There are errors in the syntax but this still should not result in a segfault.

Begin code ---------------------

namespace a
{
   struct exception_base
   {
	 virtual ~exception_base() throw();
   };
}

a::~exception_base() throw(){}

End code --------------------------------


Command line: 
> g++ -v -c -o bug.o bug.cc -save-temps

Comment 1 Richard Biener 2008-04-30 10:24:13 UTC 
g++-4.1 -S t.C
t.C:9: error: scope 'a' before '~' is not a class-name

works for me since 4.1.2.
