Aha, -DTAKE_ADDR fails when I use ld.bfd instead of ld.gold, I assume you do that too? I still don't see a difference with using -Wl,-z,now though...

I fail to reproduce the issue with the provided test case on ArchLinux. When I compile the three variants, I always properly detect the free calls.

middleton added a comment to D9259: fix heaptrack_inject to find second kind of relocation.

I was curious enough to figure out what compiler behavior causes the different type of relocation entries, so here's a test program with extensive comments. I was originally seeing the behavior with libcairo, but this should make testing easy.

mwolff added a comment to T1841: heaptrack: support debuglink and UUID for split debug info.

A WIP for this can be found in wip/buildid, it will include the buildid in the heaptrack file. But for interpreting, it isn't enough to just load the debug file only. It has to be used in addition apparently, which isn't possible without patching libbacktrace like is done in vogl.

mwolff added a comment to T1768: heaptrack: trackers for more APIs.

We should look at rr, and how they monkey-patch the vdso to trace all syscalls. That could be used then to track I/O and futex stuff. It would also be useful for heaptrack itself to trace mmap/munmap/sbrk to check heapspace vs. the "real" requested memory by the allocator.
