derwin problems

[Scott Beck]

Hey,

I'm having trouble with resizing derived windows (and subwindows for that
matter). I get a segmentation fault, usually in free() or malloc(). Here
is a bt from one of the segfaults:

#0  0x400e90f9 in chunk_realloc (ar_ptr=0x40181cc0, oldp=0x8052778,

I've created a fairly simple program that does this. If you would like I can
attach it (I wasn't sure if you can have attachments in this list).

If anyone has seen this or knows a work around I would appreciate the feedback.

/home/sbeck# ldconfig -v  |grep ncurses
        libncurses.so.5 -> libncurses.so.5.2


Cheers,

Scott
