The followin shows the OK, you're using AIX - what's the C++ compiler involved? Is it GCC, and if so what version? > behavior: > --------- > GNU gdb 5.3 > Copyright 2002 Free Software Foundation, Inc. > GDB is free software, covered by the GNU General Public License, and you are > welcome to change it and/or distribute copies of it under certain conditions. > Type "show copying" to see the conditions. > There is absolutely no warranty for GDB.
