To serialize a scroll view with NSKeyedArchiver doesn't seem to work well
when this view was loaded from a gorm file. The crash doesn't happen
immediately but a bit later.
I attached a test app that shows the problem.
When you run the test app, no exception is logged. However when the same test
app is run inside GDB with a breakpoint on -[NSException raise], GDB stops on
an exception.
NSArchiver appears to work fine as no exception can be detected with or
without GDB.
The code that leads to the crash is:
[NSKeyedArchiver archivedDataWithRootObject: scrollView]
If I create a simple scroll view with [[NSScrollView alloc] initWithFrame:]
and tries to serialize it, GDB breaks on -[NSKeyedUnarchiver
unarchiveObjectWithData:] rather than on the archiving phase as described
previously. So the issue doesn't seem to be only related to the nib/gorm
loading.
Here is the test app stack trace:
