New submission from Francois Tigeot <ftig...@wolfpond.org>: Some C++ programs with a long list of registered destructors in .so crash on DragonFly 2.8 and 2.9 systems.
The crashes seem to occur in __cxa_finalize from /usr/src/lib/libc/stdlib/atexit.c Program received signal SIGSEGV, Segmentation fault. 0x0000000801535510 in ?? () (gdb) bt #0 0x0000000801535510 in ??

Just a bit later, the FreeBSD guys fixed a similar issue with C++ dynamic shared objects. We should pick-up the changes they made in revisions 1.11 and 1.12 of their atexit.c : http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/stdlib/atexit.c?f=u&only_with_tag=MAIN&logsort=date ---------- keyword: libc messages: 9672 nosy: ftigeot priority: bug status: unread title: C++ programs crash in libc __cxa_finalize _____________________________________________________ DragonFly issue tracker <b...@lists.dragonflybsd.org> <http://bugs.dragonflybsd.org/issue2012> _____________________________________________________
