Hi,

I have a application where I am using ncursers, but I am facing a
strange
problem,
I have 2 systems as mentioned below:-

SYSTEM1: gcc version 2.95.4
address@hidden:~$ gcc -v
Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs
gcc version 2.95.4 20011002 (Debian prerelease)

SYSTEM2: gcc version 3.3.5
address@hidden:~$gcc -v
Reading specs from /usr/lib/gcc-lib/i486-linux/3.3.5/specs
Configured with: ../src/configure -v
--enable-languages=c,c++,java,f77,pascal,objc,ada,treelang
--prefix=/usr
--mandir=/usr/share/man --infodir=/usr/share/info
--with-gxx-include-dir=/usr/include/c++/3.3 --enable-shared
--enable-__cxa_atexit --with-system-zlib --enable-nls
--without-included-gettext --enable-clocale=gnu --enable-debug
--enable-java-gc=boehm --enable-java-awt=xlib --enable-objc-gc
i486-linux
Thread model: posix
gcc version 3.3.5 (Debian 1:3.3.5-13)

The Application gets compiled in both the systems, but the binary form
SYSTEM1 displays garbag as you can see in the attachment, but the
binary
form SYSTEM2 is working fine, but in the both case the ncursers in
leaking
memory(Used Valgrind for checking) which I am attaching below:-
