      Compile a program attached in how-to-repeat section with
      c++ -g -ggdb foo.cc

      Run it in gdb. Exec:
      b main
      p sizeof(bool)
      p sizeof(foo)
      p sizeof(bar)
      p &foo
      p &bar
      set foo=1
      set bar=0
      set foo=1

      Note, that nevertheless pritnf() output is correct.

Environment:
System: Linux oak 2.4.21-99-athlon #1 Wed Sep 24 13:34:32 UTC 2003 i686 athlon i386 GNU/Linux
Architecture: i686

OS: SuSE Linux 9.0, GNU gdb 5.3.92 from default package. Note, that the bug
reproduces on the other developers SuSE 9.0 boxes, having earlier versions of
GCC.

host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc-3.3.2/configure --enable-threads=posix --enable-languages=c,c++

How-To-Repeat:
     -- cut (foo.cc) 
#include <stdio.h>
extern bool foo;
bool foo, bar;

int main()
{
  printf("%d, %d, %d\n", sizeof(bool), sizeof(foo), sizeof(bar));
}
     -- end cut
------- Additional Comments From konstantin at mysql dot com  2004-02-09 10:01 -------
Fix:
    Work around is not use bool if bool is extern, because they are not
    operable in debug mode.
