fix_uninitialized_memory.patch Edit (324 bytes, text/plain)

Caused by a variable not being initialized in open_existing_wfile. The attached patch fixes the problem.

The same problem also exists in the package putty-tools to which the attached patch can be applied as well (correct paths in the diff if needed).
