One of my programs, which was working quite well till now, suddenly gives me the error: *** glibc detected *** double free or corruption (top): 0x0808a338 *** Aborted It is a pure C program compiled with GCC 4.02 -- I do not understand why it does not work suddenly. Please tell me what the above error can be.
