Greg, Yes, the heap should have been corrupted. Instead of using valgrind, I chose to review my code again. And found that 'gss_buffer_desc' passed to 'gss_import_name' had the `length' set to 'strlen() + 1' with the terminal '\0' included. Probably it is the cause of the heap corruption. many thanks :-) On Mon, Oct 26, 2020 at 3:39 AM Greg Hudson <[email protected]> wrote: > On 10/25/20 1:31 AM, Ming Zhi wrote: > > I have encountered a very rare situation, that the libkrb5 raised an > > exception with the message "malloc: invalid size (unsorted)", and the > host > > process quit afterwards. > > This message is an indication that the heap was corrupted prior to the > malloc() call.
