I found a similar bug upstream.

The issue was solved for me after these steps : 1. Re-emerge apache without distcc and distcc-pump features (even if no distributed compilation was possible in last emerges) At this point, apache was not working either, but with a different error 2. Uninstall apache, re-emerge apr, apr-util, and apache in this order, as suggested by this wiki : https://wiki.gentoo.org/wiki/Project:Apache/Troubleshooting#Apache_is_returning_zero-length_pages_or_segfaulting
Yep, confirming. The segfault is gone after rebuilding apr, apr-util, and apache in this order without FEATURES="distcc distcc-pump". I rebuilt them just to test, since I'm using www-servers/lighttpd instead. Thanks anyway.
are you still hitting this with newer versions?
Having never experienced the issue myself, I can only guess, but: this is probably a binary compatibility issue between www-servers/apache and dev-libs/apr. There is some good upstream documentation at https://apr.apache.org/versioning.html#binary that suggests an "x.y" subslot might be used for versions "x.y.z" of dev-libs/apr. Then www-server/apache would use a subslot dependency to force a rebuild with either the "x" or "y" component of dev-libs/apr changes. For example, dev-libs/apr-1.6.3 would have SLOT="1/1.6". The versionator eclass could be used to extract the "1.6" from ${PV} automatically.
A quick grep shows that a number of other packages might benefit from a subslot dependency, if we add the subslot to dev-libs/apr, Apache stuff: * app-admin/apache-tools * dev-libs/apr-util Misc: * dev-util/kdevplatform * dev-vcs/kdesvn * dev-java/netty-tcnative * dev-java/tomcat-native * dev-libs/log4cxx A few other packages (like www-servers/nginx) already use ":=" or ":1=" in their dependencies, even though we have no subslot for dev-libs/apr yet.
We should then probably revbump dev-libs/apr to add a subslot and start depending on that subslot, right?
@pacho: it's been a few months, but I think that's what I was suggesting =)
OK, I was tempted to go ahead and revbump apr for adding the subslot but wanted to be sure ;)
[master a53bb50a5f4] dev-libs/apr: Setting a subslot is needed (#525222) 1 file changed, 147 insertions(+) create mode 100644 dev-libs/apr/apr-1.6.3-r1.ebuild
Now that dev-libs/apr has a sub-slot and consumers make use of it I suppose this bug can be closed.
