User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050923 Fedora/1.7.12-1.5.1
Description of problem:
Upon running vncpasswd, and entering the correct passwords 3 times over, vncpasswd refuses to change the password. glibc error with stack trace is displayed.
Here is a small excerpt, the full output will be as an attachment:
Passwords don't match - try again
*** glibc detected *** vncpasswd: free(): invalid next size (fast): 0x09711130 ***
======= Backtrace: =========
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run: vncpasswd
2. Type password twice
3. Recieve a backtrace stacktrace
Actual Results: vncpasswd failed to change a password for the vncserver application in vnc-server-4.1.1-10.1
Expected Results: Password should have changed, and been immediately usable, as far as I know.
Could be something on my machine.
I am not absolutely certain, and with the conflicting reports I sometimes get from bugzilla responses, I am still unsure. I however do not think my glibc packages are broken, if they were I think I'd be seeing many more problems.
Just a guess.

Sounds like a duplicate of bug #160471. The work-around is to limit your
password to 8 characters. (Characters beyond that are ignored anyway.)
