[E-devel] Evas built with threads enabled causes enlightenment to hang.

[Ralph S. <gen...@bl...>]

Hi all,

I use the live ebuilds from the efl repository to install
enlightenment. When I enable the threads use flag enlightenment hangs
at startup. Actually it's only the option --enable-async-render which
when set causes the hang. The problem persists for at least 2 weeks.

Some system informations to work with:

Attached to the mail there are the full outputs to stderr of both
builds of evas. If there is anything else I can provide to help find the
problem please ask.

Cheers.
