      Description

      This only affects decimal(38)

      There are two known issues caused by -OX flags of gcc.
      GCC <= 9.2 with -O2 tends to use movdqa instruction for int128_t asignment operations that fails on unaligned memory addresses. Here is some information.

      There is an issue with count(distinct d1) expressions used in projections. Repetitions of the query produces different results for the same data set.

      SELECT count(distinct d1) FROM cs1;
