Prevent an implicit int promotion in malloc/tst-alloc_buffer.c
According to ISO C11, section 6.5.3.3 "Unary arithmetic operators", the result of the ~ operator is the bitwise complement of its (promoted) operand. This can lead to a comparison of a char with another integer type. Tested on powerpc, powerpc64 and powerpc64le. * malloc/tst-alloc_buffer.c (test_misaligned): Cast to char before comparing with another char.
