+===== Compiler warnings =====
+Unfortunately is the GNU Fortran compiler not on the same level concerning warnings as its C/C++ counterparts. Especially the ''-Wunitialized'' which is part of ''-Wall'' may give spurious warnings of the following kind when building together with ''-O1'' (or greater):
+<code>
+attention : ‘arr.offset’ may be used uninitialized in this function [-Wuninitialized]
+attention : ‘arr.dim[1].stride’ may be used uninitialized in this function [-Wuninitialized]
+attention : ‘arr.dim[0].ubound’ may be used uninitialized in this function [-Wuninitialized]
+</code>
+This is tracked at GNU/gfortran upstream here [[https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66459|Bug 66459]] and [[https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60500|Bug 60500]]
