BlitzMax Application and MacOS X 10.5.6

I am creating an Application under MacOS X 10.4.11. I friend has tested then Beta on a Mac Pro with MacOS X 10.5.6 and it crashes.

This is the Crash Report:

The crashreport is a little bit longer than here. Has anyone an idea.
I should be a problem with writeline. If i remove the lines from my source it does not crash under MacOS X 10.5.6, under MacOS X 10.4.11 it works fine.
I have read that under MacOS X 10.5.X the Applications have an uuid in the info.plist?

Only thing I can think of is that the stream you are writing to is not valid (eg. open).
In debug mode it should stop you :

		Assert _cstream Else "Attempt to write to closed stream"
		Assert _mode & MODE_WRITE Else "Attempt to write to read-only stream"

Although, looking at the code, I think it is broken :-p
Should probably rather say :

		Assert _cstream, "Attempt to write to closed stream"
		Assert _mode & MODE_WRITE, "Attempt to write to read-only stream"

Ok. I have installed MacOS X 10.5.6 and it work. My friend have tested this on his machine and it does not work. Is is possible that some application enhancer kill the blitzmax application.

Hi,

Can you post some code for us to try out?
