There is reading one byte past the end of the input buffer in binascii.b2a_qp(). Following example shows the behavior difference depending on the value of this byte: >>> binascii.b2a_qp(memoryview(b'..')[:-1]) b'.' >>> binascii.b2a_qp(bytes(memoryview(b'..')[:-1])) b'=2E' In rare cases (memoryview of mmap object or custom buffer) this can cause a segfault. Maybe there are similar issues with other binascii functions (not checked).
