--- Comment #4 from Wenzel Jakob <wen...@mitsuba-renderer.org> ---
Hmm, it looks like this is still an issue. Recompiling my codebase with the
latest trunk version of gcc still produces many errors caused by this, e.g.
include/simdarray/array_avx512.h:1059:53: error: invalid conversion from
‘simd::ArrayOperations<unsigned int, 16ul, false, (simd::RoundingMode)4,
simd::Array<unsigned int, 16ul, false, (simd::RoundingMode)4> >::Scalar* {aka
unsigned int*}’ to ‘const int*’ [-fpermissive]

etc...
