Subject: [PATCH v2] gdb/testsuite: add regression test for per-objfile typeprinters
Date: Mon, 27 Feb 2023 12:12:01 +0100 [thread overview]
Message-ID: <20230227111201.4092957-1-blarsen@redhat.com> (raw)
PR python/17136 reported an unhandled exception when using typeprinters
only valid on some objfiles, rather than being a global typeprinter. The
fix was accepted without a regression test, and we've been carrying one
out-of-tree for a while but I think it's worth upstreaming. The code
itself was developed by Jan Kratochvil.
