Hi, Valgrind just told me that Python calls close(-1) on my_mmap_object.close() for memory mappings. That's because a memory mapping has no (related) file descriptor. Using attached warn.py, you can see the warning using strace: $ strace -e close python warn.py 2>&1|grep -A1 12345 close(12345) = -1 EBADF (Bad file descriptor) close(4294967295) = -1 EBADF (Bad file descriptor) close(12345) = -1 EBADF (Bad file descriptor) where close(4294967295) means close(-1). Attached patch fixes this warning. |
