Could be closed as media-libs/libjpeg-turbo-1.4.0 is no longer in tree and 1.5.0 is stable across all arches?
Yeah. Looking at the eror the bug is in gcc's instruction selector. I can't reproduce it on modern ppc (gcc-6.4.0, gcc-5.4.0). Tried as: CFLAGS="-O2 -mcpu=powerpc -mtune=powerpc -pipe -fdiagnostics-show-option -frecord-gcc-switches -ftree-vectorize" emerge -v1 media-libs/libjpeg-turbo Let's close it as obsolete. If you still can reproduce it please let us know and we will try to track it down. gcc internal compiler errors (ICEs) are usually easy to shrink down to something palatable to fix upstream.
