The sprintf() format string in t/local/ptr_cast_test.c is trying to cast
an unsigned long as a regular int and this causes the test suite to fail:
t/local/00_ptr_cast.t .......... 1/5
# Failed test 'STDERR empty after compiling'
# at t/local/00_ptr_cast.t line 28.
# got: 't/local/ptr_cast_test.c: In function ‘main’:
# t/local/ptr_cast_test.c:27: warning: format ‘%d’ expects type ‘int’,
but argument 4 has type ‘long unsigned int’
# t/local/ptr_cast_test.c:27: warning: format ‘%d’ expects type ‘int’,
but argument 6 has type ‘long unsigned int’
# '
# expected: ''
# Looks like you failed 1 test of 5.
An easy workaround is to change the format string on line 26 to use %lu
instead of %d.
