+Subject: [PATCH 1/2] Avoid calling AVX code in library static initialization
+
+Despite 26072b8db7ba53f00c83197cb064229a76001989 and
+12c6b1ef6a824b09778163ec83fc44bb196e65db, Linux builds using
+RH devtoolset-7 gcc7 still hit occasional unit test crashes
+with illegal instructions.
+
+Backtrace is always:
+
+> #0  __static_initialization_and_destruction_0 (__initialize_p=1, __priority=65535) at core/sc/source/core/tool/arraysumAVX.cxx:20
+> #1  _GLOBAL__sub_I_arraysumAVX.cxx(void) () at core/sc/source/core/tool/arraysumAVX.cxx:112
+>
+
+So lets make sure initializer is run only on function entry.
