> Subject: g++ 2.1 global object instance initialization problem

Problems in the C++ part of the compiler should go to
bug-g++@prep.ai.mit.edu, not this list.

Your problem should be solved in the next release of gcc.

> PROGRAM: g++  SUBPROGRAM: cc1plus
> VERSION: 2.1
>  SYSTEM: Sun 4/40 (IPC)
>      OS: SunOS 4.1.1 Rev B.

> LOCAL INSTALLATION:
> gcc 2.1 was installed by patching the 2.0 distribution
> with the gcc.diff-2.0-2.1 file. The following commands were then
> issued to build and install the new release:

>   configure sun4
>   make LANGUAGES=c
>   make stage1
>   make CC=stage1/gcc CFLAGS="-g -O -Bstage1/"
>   make stage2
>   make CC=stage2/gcc CFLAGS="-g -O -Bstage2/"

>   for file in *.o; do
>   cmp $file stage2/$file
>   done

>   make CC=stage2/gcc install
>   make install-fixincludes

> All of the above commands were successful.

> BUG DESCRIPTION:

> The problem occurs when I try to use global instances of C++ objects
> with constructors as initializers.

> Here's an example of a global object array initialization. The
> following C++ code example (which I condensed from a much larger source)
> causes a signal 11, Segmentation fault, when compiled with g++ 2.1 on
> my system.

> -- Begin itest.cc

> class X {
>     int i1;
>     int i2;
>   public:
>     X(
>       int ii1,
>       char ii2
>       )
>       {
> 	  i1 = ii1;
> 	  i2 = ii2;
>       }
> };

> X x[] = { X(1, 2) };

> -- End itest.cc
