[Interest] QResourceRoot::findNode Crash on OS X

[Jason A. Donenfeld]

Hello Qt-Interest,

I have an application that at some point calls

        QFile file(":/MyProgram.ui");
        file.open(QFile::ReadOnly);

These lines cause this segfault on OS X:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x00000000fd05de65
0x00000001037da399 in QResourceRoot::findNode ()

The application makes use of shared libraries for functionality, and the
shared library as well as the main executable has its own resource files.
If the shared library does not have resources compiled in, this problem
does not occur.

This problem does not exist on Linux or Windows.

Evidently the two resource loads are stepping on each others' memory
spaces. Does anyone know how to make them play nicely with each other? Or
is this simply not possible, and I will instead have to put all my
resources in a single place?

Thank you,
Jason
