Hello,

gdb-archer segfaults on me at a certain point in my source code.  To give a 
proper bug report I did wanted to get a backtrace.  So I did
  ulimit -c unlimited
to get a core dump.

However, I all I get by running my systems gdb-6.8 on the core file
  gdb --core=core
is
{{{
$ gdb --core=core

}}}

Can you guys give me a hand on how to move forward from here?


Thanks,

PS: I configured archer with
{{{
  export CFLAGS=" -g -O1 "
  export CXXFLAGS=" -g -O1 "
  ../configure --enable-debug \
      --prefix=/usr \
      --disable-nls \
      --mandir=/usr/share/man \
      --disable-werror \
      --infodir=/usr/share/info
}}}
ran make but didn't install it.
