Note that this leaves the perf build against libunwind in the current, broken state. I do not know how to detect the activation property there. Does anyone else? See elfutils source code for what it is doing: https://sourceware.org/git/?p=elfutils.git;a=blob;f=libdwfl/ dwfl_frame_pc.c;h=296c815b9c73f42d79ac1778d2a0c420b89ee4eb;hb=HEAD Cheers -- Milian Wolff | milian.wolff@kdab.com | Software Engineer KDAB (Deutschland) GmbH&Co KG, a KDAB Group company Tel: +49-30-521325470 KDAB - The Qt Experts
