Test case

The test case, which works under PyQt4, illustrates the problem. Although it is
not clear exactly what is going on, it seems that garbage collection is
interfering with some internal Shiboken process.

The test script segfaults immediately on PySide 1.0.5.

Comment 1 Hugo Parente Lima 2011-08-02 23:58:23 EEST

It segfaults here in 8/10 runs.

Comment 2 Evan Patterson 2011-08-11 19:36:05 EEST

Would be possible to get an ETA on a fix for this?

Although the test case is perhaps a little unusual, the bug is serious in that
it breaks practically all of the Enthought Tool Suite (ETS) under PySide. Also,
this seems to be a regression; I cannot reproduce the crash on PySide 1.0.3.

Thanks.

Comment 3 Hugo Parente Lima 2011-08-11 20:49:25 EEST

It should be fixed before the next release, being a regression I'm rising the
priority to P1.
