https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237195 --- Comment #8 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to freebsd from comment #5) It sounds like an access to the freed memory. Anyway, it is somewhat labor-intensive to read disassembly to track your issue, and since you did not disassemble the whole functions bodies, it is impossible. Compile libc/libthr/rtld with debugging enabled: make -C lib/libc DEBUG_FLAGS=-g all install same for lib/libthr, libexec/rtld-elf. Then reproduce the issue and show the backtrace with debugging symbols, so that the source line numbers are easily seen. -- You are receiving this mail because: You are the assignee for the bug.
