More precisely, segmentation fault occurs with -ftree-loop-vectorize
and at least -O1
(so either CXXFLAGS="-O1 -ftree-loop-vectorize"
or CXXFLAGS="-O2 -ftree-loop-vectorize"
).
Segmentation fault occurs with GCC 10.2.0, and does not occur with GCC 8.4.0 or 9.3.0.
Reported as GCC bug 99375.
Problem was fixed in GCC 10 branch: GCC commit 1ab88985631dd2c5a5e3b5c0dce47cf8b6ed2f82 Fix will be released in GCC 10.3.0.
(I will close this report in Marisa after release of GCC 10.3.0.)
Segmentation fault in
marisa-test
occurs if Marisa is configured withCXXFLAGS="-O3"
. Problem does not occur for me with additional-march=westmere
or-march=native
(e.g.CXXFLAGS="-O3 -march=westmere"
). I use GCC 10.2.0.
