The binary resulting from rsyslog-3.21.5 with USE="gnutls kerberos postgres zlib -dbi -debug -mysql -relp -snmp" leads to a segfault if executed with the debuggin option (-d). In normal execution the process blocks and does not go into background (without the -n flag). strace shows the last call to be a wait call. revdep-rebuild shows no broken dependencies. Downgrading to rsyslog-3.21.4 solves the problem.

The recently released 3.21.6 might fix this issue since the changelog mentions a fixed segfault condition. See http://www.rsyslog.com/Article292.phtml for the changelog.
Bumped rsyslog to version 3.21.6, thanks for the report. I couldn't reproduce the problems with the new version. Please reopen if problem still persists.
hmm, a bit too early. Just did another test and compilation still fails with USE=debug.
Bug report @upstream: http://bugzilla.adiscon.com/show_bug.cgi?id=103
Ok, replaced $(use_enable debug imdiag) with --disable-imdiag since upstream doesn't support it anyway.
