According to the C standard, converting UT to T yields an
|
||||
implementation-defined result or signal for values outside T's
|
||||
range. However, code that works around this theoretical problem
|
||||
runs afoul of a compiler bug in Oracle Studio 12.3 x86. See:
|
||||
https://lists.gnu.org/r/bug-gnulib/2017-04/msg00049.html
|

As the compiler bug is real, don't try to work around the

theoretical problem. */
