https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=198452 Konstantin Belousov <kib@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |Works As Intended CC| |kib@FreeBSD.org Status|New |Closed --- Comment #1 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to dpejesh from comment #0) Dlopen/dlclose cannot work in the context of the dl_iterate_phdr(3) callback. At least, because the dl_iterate_phdr() walks over the list of the loaded shared objects, so in the language terms, it is the iterator over collection, and collection must be stable. The callback API does not suppose a possibitily of restart. That said, callback is intended to perform some lookups on the per object basis, e.g. enumerate exception tables, debug sections and like. The revisions you point out as causing the problem obviously mean that this never worked anyway. -- You are receiving this mail because: You are the assignee for the bug.
