>Description:
The Syscall malloc() loops infinitly when it should allocate lets say.. more than 512b of memory (on my system) but allocating only a few bytes works well. It also ran on a similar system to mine using the libncurses.so.4 - so it's either an error in gcc or in libcurses - I don't know for sure...

For further Infos and strange things have a look at the comments in the short c++ source code.
>How-To-Repeat:
g++ -lform -lcurses -o ncursesInClass ncursesInClass.cpp
and run the binary

you can use g++ 2.95 or 3.2 as well to compile.
>Fix:
no idea...
