I encountered this issue when investigating some GCC test failures when 
using FLAT. I don't remember if they were in GCC Fortran testsuite. Some 
variables in those test cases were required to be aligned at a large 
boundary, for example 16-byte. I found 0x20 was a reasonably large 
alignment to fix all such failures in GCC testsuite.
