Description Bloody 2016-02-15 01:22:33 UTC

Hello everyone,

I have segfaults with lz4 (CLI 64-bits R120) using the -9 -BD option combo with certain small-ish files, like e.g.: /usr/share/apps/LICENSES/GPL_V2

Command:
  lz4 -9 -BD GPL_V2 GPL_V2.lz4

Compiled with gcc (Gentoo 4.9.3 p1.3, pie-0.6.3) 4.9.3

Happens with -O3 as well as -O2.

Can anyone confirm this?

Could you retry with the most recent release (_p131)? If it still happens, please attach the problematic file (I don't really know where /usr/share/apps/LICENSES could come from).
