hii I m a newbie to the GTK toolkit ,using it to make a front end for an application designed in C .The front end when used stand alone is working fine and so is the C code.But when copmbined together and run ,then its causing a memory corruption in malloc and sometimes fclose functions when i disable the gui in the program then the result is as expected.
the error i m getting is
*** glibc detected *** malloc(): memory corruption (fast): 0x08153c20 ***

also if i skip a window or cut the series short then the memory corruption is shifted to later stages of the program but do take place
I m working on suse 9.3
compiling application with `pkg-config --cflags --libs gtk+-2.0`

i cant paste the code here due to size consideration

Is thr something that i m doing wrong with my coding or this is a bug .Please if anyone have any idea what i m doing wrong then help me
thx
