[Bug debug/29906] New: -d option creates internal compiler error

[axel-freyn at gmx dot de]

without "-d" -option, the code compiles cleanly and works.
with "-d", the compiler crashs:
bug.cc:5: internal compiler error: in force_type_die, at dwarf2out.c:12904

the file bug.cc:

struct A{
  typedef int T;
  virtual ~A();
};
struct B:public A{
  using A::T;
};


The error occurs with versions
gcc version 4.1.2 20061028 (prerelease) (Debian 4.1.1-19)
gcc version 4.0.4 20060904 (prerelease) (Debian 4.0.3-7)
gcc version 4.1.0 (configured with: ../../gcc_download/gcc-4.1.0/configure
--prefix=/home/abf/gcc --program-suffix=-4.1)

the older versions
gcc-Version 3.3.6 (Debian 1:3.3.6-13)
gcc-Version 3.4.6 (Debian 3.4.6-4)
work

Janis could you do a regression hunt to find what caused this bug and what also
fixed this bug on the trunk?

A regression hunt on powerpc-linux identified this patch for which the testcase
started failing on mainline:

Another regression hunt on powerpc-linux identified this patch for which the
testcase started passing again on mainline:

-g -fno-emit-class-debug-always will produce the same effect on the mainline
and the 4.2 branch so I am going to say this is still a 4.2/4.3 Regression.
