Comment (by chris.cooper@…):

 This behavior causes the regression test to fail inaccurately.

 Unfortunately, it's a bit of a pain to easily modify this regression test
 to limit the input parameters to test_left_shiftable() to ones that will
 not encounter the compiler's "undefined behavior".  Consider removing
 test_left_shiftable() from test_all() and make a special testing loop that
 calls it, passing a different set of random numbers guaranteed to be valid
 left-shift parameters ...
