I made a reference to this in bug number 14061. I've done some further debugging while trying to come up with an new ebuild for inn 2.3.4. The problem is that the first malloc seg faults, but only when inn is built with perl. Deleting the --with-perl line in the ebuild resolves the problem. Recreating this is very easy. All that is necessary is to emerge the current ebuild for inn (with an inherit debug at the top) and debug the innd program. It seg faults in the first few lines attempting the first malloc. At first, I thought it might be some kind of threading problem. Libperl is not built with threads by default and inn doesn't use threads but links with the thread libraries if configure finds them (for the future). But building inn without threads didn't resolve the problem. I would like to have someone with more perl internal and/or system library experience look at this.
should be fixed with 2.3.5 if not, please report a new bug
