On Loading crystal reports I get "Buffer too small for string"

[Guest]

When loading crystal reports in my windows applications(created using Visual
C#), I get an error "Buffer too small for string or missing null byte".

I tried various things i.e. increasing the field sizes in crystal reports,
but still get the same error.

I create a new crystal report using Visual C# and then added a Windows Form
Viewer in a Windows Form. I then hosted the crystal report on the Windows
Form Viewer.

Any help or advice will be greatly appreciated.
