when emerge samba with the debug-useflag, /usr/sbin/smbd, /usr/bin/net, /usr/bin/smbclient and possibly others wont start but Segfault right away. dmesg says the following: nmbd[30139]: segfault at 7fffe18fcff8 ip 00007f96868d7f03 sp 00007fffe18fd000 error 6 in libc-2.15.so[7f968685d000+19f000] smbd[30156]: segfault at 7fffe8515ec8 ip 00007ffcb0d873f2 sp 00007fffe8515da0 error 6 in libc-2.15.so[7ffcb0d40000+19f000] smbclient[32017]: segfault at 7fffb431efd8 ip 00007f181676f508 sp 00007fffb431efe0 error 6 in libc-2.15.so[7f1816672000+19f000] net[28555]: segfault at 7ffff2657f68 ip 00007f828efe54dd sp 00007ffff2657ee0 error 6 in libc-2.15.so it's possibly some glibc-thing, but as i said: just doing USE="-debug" will fix this problem. just posting this so others will not spend ours debugging the debug-useflag as i did ;) Reproducible: Always Steps to Reproduce: 1. USE="debug" emerge samba 2. smbd | smbclient | net Actual Results: Segmentation fault Expected Results: good ol' samba performing
1) Please post your `emerge --info net-fs/samba' output in a comment. 2) Obtain a gdb backtrace and post the result on this bug report.

IMHO the bug is in the dmalloc or near it.
