In the simple example I provided, it always works. I have added loaded modules with conflicting symbols and dladdr() also works as expected. But for my main application (which populates backtraces with dladdr), musl dladdr() works in DEBUG mode and crashes in RELEASE mode. I did not have time to isolate the problem in a reproducible code snippet but I will let you know when I have done that. Knowing that dladdr() crashes should help you anyway: it might be related to searching addresses that are out of the specified module scope (stack smashing?), or to the ability to be resilient to introspecting itself (hence the success of the musl DEBUG code, as well as of the bulky GLIBC). I don't use BSD so I can't tell what they _do_. I appreciate musl and intend to contribute, especially in the areas where my application is using libc in cornersome areas. I also find the idea of a musl-based Linux distro rather attractive as it will immensely reduce the surface of uncertainty. Pierre
