[PATCH] gdb.pascal/stub-method.exp
- From: Doug Evans <xdje42 at gmail dot com>
- To: gdb-patches at sourceware dot org, pierre dot muller at ics-cnrs dot unistra dot fr

- Subject: [PATCH] gdb.pascal/stub-method.exp
- Authentication-results: sourceware.org; auth=none
Hi.
This patch is based on the testcase provided here:
https://sourceware.org/ml/gdb-patches/2015-02/msg00181.html
I've verified that it catches the internal error discovered here:
https://sourceware.org/ml/gdb-patches/2015-02/msg00139.html
One needs to make sure one is compiling with stabs.
How to do that for pascal is a topic for a separate patch.
