Hi,

Anyone seeing this as well? sort goes berzerk on my system when piped into
head (or less) when it is fed with a 'specially prepared' input file.

 - only happens on x86_64
 - does not happen for 'LC_COLLATE=C sort tt | head'

'specially prepared' input file? (see bottom of post).

Henri

 note: sort.exe cannot be killed using 'kill -9'
 note: sort.exe is using a high amount of CPU ... (loop?)
 note: file tt is obtained as follows ./genfl.sh > tt (see bottom of post)

# sort is terminated from another instance of bash, using:

SUCCESS: The process "sort.exe" with PID 3680 has been terminated.
