Package: coreutils
Version: 5.97-5.3
Severity: normal
While running cut over some screen logs (which include escape
characters), I managed to cause cut to segfault with the message:
*** glibc detected *** double free or corruption (top): 0x0000000000507320 ***
The backtrace isn't particularly helpful either:
Core was generated by `cut -f2 -d( file0 file1'.
Program terminated with signal 6, Aborted.

I've attached a test case that consistently elicits the behavior
from cut on my unstable amd64 machines. Simply run the 'test.sh'
script.
