[Bug 1353469] Re: Compiler optimization error needs investigation
Doko, you asked me to re-test if this is still a problem. It is. :( I
rebuilt accountsservice with latest utopic and without the optimization
work-arounds I had put it in it before. Still hit bug 1351308.
** Changed in: gcc-4.9 (Ubuntu)

Bug description:
This is a breakaway bug from bug 1351308.
accountsservice 0.6.37-1ubuntu7 introduced a new bug where
libaccountsservice would not report the manager object as loaded. It
wasn't because of the content of that upload, but rather seemingly
because of building with a new compiler. It got uploaded shortly
after the gcc 4.9 transition.
I wasn't able to determine whether this is something accountsservice
is doing or just gcc's fault. But even inserting some debug
statements around the place or downgrading optimization to -O1 made
the problem go away. So I'm leaning towards gcc.
For now, we just changed optimization in the package to workaround the
problem. But the root source should be investigated.
