Description Andrew Savchenko gentoo-dev 2012-05-13 06:11:52 UTC

showstats without arguments or with -v segfaults.
This happens when compiled with -O1 or higher, works with -O0.

Further investigation shows that sscanf was used with the violation of the C standard: source and destination buffers were overlapping. Proposed patch fixes this, I send it upstream to mauiusers mail list with no reply, ML looks stagnant.
