[Bug 1353469] [NEW] Compiler optimization error needs investigation
Public bug reported:
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.
** Affects: gcc-4.9 (Ubuntu)
Importance: Undecided
Status: New
** Package changed: accountsservice (Ubuntu) => gcc-4.9 (Ubuntu)
