ncurses Ubuntu 64bit

[tjareson]

Hello,

are there any special configurations or settings to consider, when 
compiling ncurses and forms in a 64 bit environment? Or any known pitfalls?

I've tried to compile an application which uses forms (also using wide 
characters) which compiles and runs without any problem in an Ubuntu 
32bit evironment.

When I compile and run exactly the same setup (ncurses 5.9) on the 
Ubuntu 64bit environment, the application causes a segmentation fault, 
whenever a character is typed into a forms field.
When I switch between fields with cursor keys everything work, only when 
the formsdriver get called with a character the thing crashes.

Has anyone hints for me, where I should have a look into?

regards
Tjareson
