Hi,



There might be a bug in the “sort” program in GNU coreutils 8.4, present at
least in CentOS 6 x86_64.  It’s not immediately obvious to me whether or
not this bug has been reported before.



Given the following:



CC = gcc

CC = aCC

CCFLAGS =

CC = cc



sort (GNU coreutils) 8.4 yields:



CC = aCC

CC = cc

CCFLAGS =

CC = gcc



… the 3rd line is out-of-order.  In comparison, sort (GNU coreutils) 8.14
in cygwin yields:



CC = aCC

CC = cc

CC = gcc

CCFLAGS =



… which is correct.
