Xcode 2.3 seems to have broken static object destruction when my binaries
run under 10.3 (but if those binaries are built using Xcode 2.2.1, there¹s
no problems).
I have a very tiny app that loads a bundle to do everything, and when its
time to exit, the bundle is unloaded. With Xcode 2.3, my app now crashes
during its static deinit, long after my bundle has been unloaded, indicating
that my bundle's static objects are being destroyed on app exit (rather than
on bundle unload). Again, this crash *only* occurs on 10.3 (not 10.4) and
it does *not* occur if my binaries are built with Xcode 2.2.1.
The Xcode 2.3 "GCC 4.0" release notes discuss the flag -fuse-cxa-atexit
which suggests that 2.3 definitely has changes in this area, but what is
clearly a concern is why would 2.3 cause things to break -- and only on
10.3? I tried sticking in -fuse-cxa-atexit for both my app and bundle
projects but there was no change.
Stuff like this really eats me up, so if anyone can offer some assistance on
this, I'd really appreciate it! Help! Calgon, take me away!
Thanks,
Andy
