Jan Beich (mail not working) <jbeich at FreeBSD.org> has reassigned Bugzilla
Automation <bugzilla at FreeBSD.org>'s request for maintainer-feedback to
multimedia at FreeBSD.org:
Bug 216718: multimedia/ffmpeg: clang 4.0 crashes with -O3 -march=native
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=216718



--- Description ---
ffmpeg already passes -O3 by default as part of OPTIMIZED_CFLAGS option, so
only CPUTYPE?=native in make.conf was something new.

Assertion failed: (isLoopInvariant(Operands[i], L) && "SCEVAddRecExpr operand
is not loop-invariant!"), function getAddRecExpr, file
/usr/src/contrib/llvm/lib/Analysis/ScalarEvolution.cpp, line 2963.
cc: error: unable to execute command: Abort trap
cc: error: clang frontend command failed due to signal (use -v to see
invocation)
