Hi, It isn't a problem on fedora because it uses RPATH and it checks for all the loaders in the list whereas in RUNPATH it only check for the current loader which libasan whose runpath doesn't have the executables runpath. The fix is to get the main_map i.e loader of the original binary which is present in the list of loaders. It fixes my issue . I posted a patch on libc-dev but got no response.
I can post the patch here if needed. I've posted the patch at https://sourceware.org/pipermail/libc-help/2021-February/005684.html This issue is reported here as well. https://bugs.llvm.org/show_bug.cgi?id=27790 https://bugzilla.redhat.com/show_bug.cgi?id=1449604
