Hi, I'm currently getting strange SEGVs from malloc on a UltraSPARC-IIIi (V440) (see below), no matter whether src is compiled with -m32 or -m64. Especially with -m64 and even -xmemalign=1i alignment errors seem to happen frequently. [Hmmm - 'til today I thought, at least 1i gets rid of all alignment errors (Compiler is SS12u1).]
Problem source is sendmails libmilter: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/sendmail/libmilter/engine.c http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/sendmail/libmilter/comm.c t...@150 (l...@150) terminated by signal SEGV (no mapping at the fault address) 0xff2570a8: t_splay+0x0010: ld [%o2 + 8], %o1 Current function is dec_argv 1764 s = (char **)malloc((nelem + 1) * (sizeof *s)); (dbx) where current thread: t...@150 [1] t_splay(0x85a04, 0x0, 0x1fffff, 0x85808, 0x0, 0xff337480), at 0xff2570a8 [2] t_delete(0x85a04, 0x1fc, 0x1fffff, 0xff256f30, 0xff3303a8, 0x0), at 0xff256f30 [3] realfree(0x85800, 0x1ff, 0xd98dc, 0x8b7a0, 0x0, 0x8a768), at 0xff256b44 [4] cleanfree(0x0, 0xe, 0xd902c, 0x0, 0xff3303a8, 0xff3392a4), at 0xff2573cc [5] _malloc_unlocked(0x28, 0x0, 0x0, 0x0, 0xfffffffc, 0x0), at 0xff256524 [6] malloc(0x24, 0x1, 0xd9fd8, 0x0, 0xff3303a8, 0xff33a518), at 0xff256414 =>[7] dec_argv(buf = 0x88459 "i", len = 68U), line 1764 in "engine.c" [8] st_macros(g = 0xfd6fbe90), line 1481 in "engine.c" [9] mi_engine(ctx = 0x81630), line 405 in "engine.c" [10] mi_handle_session(ctx = 0x81630), line 45 in "handler.c" [11] mi_thread_handle_wrapper(arg = 0x81630), line 579 in "listener.c" t...@470 (l...@470) terminated by signal SEGV (no mapping at the fault address) 0xff2570a8: t_splay+0x0010: ld [%o2 + 8], %o1 Current function is mi_rd_cmd 143 buf = malloc(expl); (dbx) where current thread: t...@470 [1] t_splay(0x85f14, 0x7f730, 0x31313638, 0x841f8, 0x0, 0x0), at 0xff2570a8 [2] t_delete(0x85f14, 0x1fc, 0x31313638, 0xff256f30, 0xff3303a8, 0x61696c5f), at 0xff256f30 [3] realfree(0x85d10, 0x1ff, 0xd98dc, 0x82c48, 0x0, 0x85d50), at 0xff256b44 [4] cleanfree(0x0, 0xd, 0xd902c, 0x0, 0xff3303a8, 0xff3392a4), at 0xff2573cc [5] _malloc_unlocked(0x8, 0xb0, 0x80550, 0x80558, 0xffffffff, 0x0), at 0xff256524 [6] malloc(0x1, 0x1, 0xd9fd8, 0xff2baaec, 0xff3303a8, 0xff33a518), at 0xff256414 =>[7] mi_rd_cmd(sd = 13, timeout = 0xfe3fbe88, cmd = 0xfe3fbea7 "D\xff\xff\xff\xfe", rlen = 0xfe3fbec8, name = 0x65730 "ClamAV"), line 143 in "comm.c" [8] mi_engine(ctx = 0x84350), line 315 in "engine.c" [9] mi_handle_session(ctx = 0x84350), line 45 in "handler.c" [10] mi_thread_handle_wrapper(arg = 0x84350), line 579 in "listener.c" Is anybody able to spot, what's going wrong here? Thanx, jel. "OT": Problem with mail filters, which use libmilter is, that they die more or less frequently and thus their results (if any) are ignored by sendmail. Good thing is, that SMF takes care to restart the filter, however those filters are more or less unreliable since they do a ~ 90:10 job, only ... :( -- Otto-von-Guericke University http://www.cs.uni-magdeburg.de/ Department of Computer Science Geb. 29 R 027, Universitaetsplatz 2 39106 Magdeburg, Germany Tel: +49 391 67 12768 _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
