This is not an issue with strawberry, but with every perl. And the behavior is kinda documented. "perldoc -f sysread" says: It bypasses buffered IO, so mixing this with other kinds of reads, "print", "write", "seek", "tell", or "eof" can cause confusion because the perlio or stdio layers usually buffers data. "perldoc -f sysseek" suggests how to implement a systell function. I suggest to close this ticket.
