Calling sort -u -S 1G file.txt > output.txt from sys-apps/coreutils-8.7 crashes sort. Increasing memory size doesn't help. The size of file.txt is approximately 1G. The program was called with other text-files with similar size and it crashes only in some cases (same file every time). I cant upload it here because of the size, but it's just a plain textfile. Reproducible: Always Steps to Reproduce: 1. call sort -u -S 1G file.txt > output.txt with a min 1G plaintext-file Actual Results: Sort crashes with "Killed" or "Segmenation fault", depending on the file. Also some sortXXXX-files in /tmp ARE NOT deleted if sort crashes! Your disk will become clobbered with trash in a very short time when sorting big files. Expected Results: NO crash!

We'll need a stack trace to debug this further. See http://www.gentoo.org/proj/en/qa/backtraces.xml
I didn't compile with debugsymbols so these ones are missing in the following backtrace. This bug only seems to happen if sort is called with "-u" option.

I've made an upstream-report..
Seems to be solved in Version 8.8, which is not stable on gentoo until now.
