File 0001-tools-bashreadline-fix-probe-for-dynamically-linked-.patch of Package bpftrace-git
From 14b83ac87608ab359f3913b86d31e6f02665f66d Mon Sep 17 00:00:00 2001 From: Anthony Iliopoulos <ailiop@suse.com> Date: Thu, 31 Oct 2024 17:56:11 +0100 Subject: [PATCH] tools/bashreadline: fix probe for dynamically linked readline Upstream-status: sent to https://github.com/bpftrace/bpftrace/pull/3564/ Fixes: bsc#1232536 When bash links against libreadline dynamically, the probe fails as the readline symbol is undefined until runtime. Fix this issue by adding a fallback probe that hooks directly into libreadline.
