Hi, I have a problem with compiling the new revision, the file Sifsegv_gc makes a call to the file Sigsegv.cpp but returns as file already allocated: ... llvm [3]: Compiling for Debug + Asserts Sigsegv.cpp build (bytecode) llvm [3]: Compiling Sigsegv.ll to Sigsegv.bc for Debug + Asserts build ( bytecode) llvm [3]: Compiling Sigsegv.bc to Sigsegv.s for Debug + Asserts build llvm [3]: Compiling for Debug...

We're been running the distribution version of Samba 3.6.9 as DC on Centos 6 for a few weeks now with a number of Samba 4 clients. We have ~20,000 machine and user accounts in our password database. We see a SIGSEGV every 24-48 hours or so in tcopy_passwd. I built a Samba 3.6.24 with debugging symbols and waited for a core file which we got this morning. Looking through the code we can see that there was a machine lookup for one of our Samba 4 servers which was handed a duff memory pointer from a memcache lo...

Hi, I just added an "archive" mbox namespace to my dovecot setup, so that people can put their old mail into a slightly more inode-friendly box. When querying the STATUS on one of these boxes, I got a sigsegv: Program received signal SIGSEGV, Segmentation fault. 0x0000000000454d24 in message_parse_header_next (ctx=0x59e500, hdr_r=0x7fbffff420) at message-parser.c:759 759 if (msg[0] == '\n' || (gdb) bac #0 0x0000000000454d24 in message_parse_header_next (ctx=0x59e500...

...r/log/rsync/log and /var/log/rsync doesn't exist or isn't a directory (or the log file can't be opened for any other reason), then there's no warning whatsoever, as rsync forks itself into the background before checking the config, opening the log file, etc. Worse still, it gets a SIGSEGV, and dumps core.

...ld.so.1`_rt_boot+0x88 Does anyone happen to know why the ustack() doesn''t show lex, yak, main and _start?

Hi all, I am trying to write a D script which would print ustack() for every program in the system receiving SIGSEGV. All the stacks printed in trap()/sigtoproc() context do not have meaningful symbols. The following solves the problem to some degree but I''d much rather have a self-contained D script. dtrace -w -n ''fbt:genunix:sigtoproc:entry/arg2 == 11/ { self->pid=((proc_t *)arg0)->...
