Description bjoern.milcke 2006-03-28 16:00:51 UTC 
Open the attached file. (As it contains random numbers it will be automatically
reloaded to avoid just loading the meta-file). Close OOo -> Assertions about
Memory Corruption in the desctructor of the SchChartDocShell (probably of the
ChartModel).

The reason why this file causes this problem is the number format of the y-axis.
It is set to ";;;" which produces empty strings for all numbers.

Empty textshapes (with empty text string and zero-width) are no longer created
in ChartAxis::CreateMarkDescr()
Comment 3 bjoern.milcke 2006-03-29 09:44:05 UTC 
To test:
Boefore the fix:
1. Load the attached document. Press F9 several times (not necessary, but maybe
increases chances for a crash)
2. Close the Office
=> In a pro Version you should get a crash-reporter or a system dialog box about
a memory error. In a non-pro Version, you should get assertions as mentioned
before, and the the crash-reporter.

With the fix:
1., 2. as before
=> The Office should quit silently. No assertions. (At least non about
memory-corruption)
