You're using a compiler from kpitgnutools.com; talk to them for support.
Or more exactly, follow the instructions at http://www.kpitgnutools.com
referred to in the error message.
When you file the bug report, they will want you to provide
a minimal test case.  This is very important.  The procedure for
creating one is as follows:

Tke command that failed from log, and turn it into a shell script
 that does
   #!/bin/sh
   PATH=...the path from the log...
   export PATH
   cd ...the directory from the log...
   [the command that failed]
Run that script, verify it fails in same way
Then add -E to the gcc command, remove -o sort.o, and
save result in sort.i
Compile sort.i and verify same error
Repeat:
  Back up sort.i
  Delete lines from sort.i
  Verify error still happens on smaller file
until sort.i is as small as possible

Post sort.i with error report
