What's the reason of error ""*** glibc detected *** munmap_chunk(): invalid pointer"

15/10/2007, 15h42

I have a C++ package which works very well in the 32-bit Linux-like
OS. However, it will lead to a "*** glibc detected *** ./ex2:
munmap_chunk(): invalid pointer" in 64-bit (Fedora 7-64), when it
delete a object generated by new operator. I really do not known
why?
And I need your . Please tell me why and when this error should
happen? So that I can fix my problem.

Me neither - mostly because I do not have access to your code.
Have you tried searching the net for that error?

Sorry, I have did the google but the explicit reason is inavaiable.

A friend has told me this may be caused by heap error. And I am fixing
it by Valgrind tool. Very thanks for your reply.

, Thanks for your reply. I am trying the Valgrind tool to memcheck.
Maybe it is a heap error.
