>Environment:
System: Linux kiste 2.4.16 #6 Wed Dec 26 16:44:07 CET 2001 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu
SuSE 7.3
glibc 2.2.4
GNU ld version 2.11.90.0.29
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc/configure --enable-shared --disable-nls --enable-threads --enable-languages=c,c++,f77,objc --enable-concept-checks
>Description:
The following source p.C causes an ice. g++ consumes all virtual
memory until the process is killed by the kernel. When the second
parameter to the a constructor is removed the code compiles
>How-To-Repeat:

Source code p.C
struct a {
   a (int, const a & = 0) { }
};

int main ()
{
  a b (0);
}

g++ -v -W -Wall p.C -W -Wall -save-temps
