It is not Windows-specific.  I reproduced it with a c++ program on my
x86 F11 box.

The program comes from PR 9032:

    #include <stdio.h>
    class InstSelection {
    public:
      InstSelection(double d) {
      }
    public:
      virtual ~InstSelection(void);
      void dump(void);
    };

    InstSelection::~InstSelection(void)
    {
    }

    void InstSelection::dump(void)
    {
      printf("InstSelection::dump here\n");
    }

    int main(void)
    {
      InstSelection *is = new InstSelection(17.0);
      is->dump();
      delete is; is = 0;
      return 0;
    }

I compiled it with the system g++, then ran CVS head gdb on the
executable.  Finally:

(gdb) b InstSelection::InstSelection
../../src/gdb/breakpoint.c:4962: internal-error: set_raw_breakpoint: Assertion `sal.pspace != NULL' failed.


The sal causing the problem in set_raw_breakpoint:

(top-gdb) p sal
$10 = {
  pspace = 0x0, 
  symtab = 0x0, 
  section = 0x0, 
  line = 0, 
  pc = 0, 
  end = 0, 
  explicit_pc = 0, 
  explicit_line = 0
}

That seems odd.
