I agree about it, a testcase is possible with unchanged FSF GDB as shown in http://sourceware.org/ml/gdb-patches/2011-06/msg00387.html but the memory corruption is too random to rely on it in a testcase. > Is there some other approach--short of rewriting all the *type_print* > stuff--that would be acceptable? I'd love to close out this problem. I find the user-facing bug as already fixed since the check-in: http://sourceware.org/ml/gdb-patches/2011-06/msg00475.html There are some outstanding problems being discussed (it is my turn now): http://sourceware.org/ml/gdb-patches/2011-07/msg00233.html but that is more for the next readline release and I hope users no longer hit these crashes. If you still have it reproducible with FSF GDB HEAD or 7.3 snapshots please provide some backtrace etc. Thanks, Jan
