Subject: W32: Fix msg allocation in gns helper service
X-Git-Tag: taler-0.2.1~48
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=903c035f7948d1c216d2d85a68458572b0b17e36;p=oweals%2Fgnunet.git

W32: Fix msg allocation in gns helper service

The code was hacky, and GCC warned about variables being used without
initialization. Turns out, it was much worse.
