In slate/tester.cpp "strcpy(mem, "trombone\n");" cause segmentation fault since char* men isn't initialized. Please fix it.

The reason may be different from what I thought before. It seems that *pointer = 0xffffffffffffffff after code "*pointer = shmat(buf_id, 0, 0);" in slateMalloc function. Do you know the reason?

It is because the key of shmget equals 0, which is read from fdin. It indicates that the file it read from is empty.

I find the accurate reason. The type of variable "size" in SlateClient::do_malloc() is int, if you change it to size_t, the bug will be solved.
