This week I finally realized where problem with random crashes in Wammu and python-gammu lies - python-gammu was using two version of C library - mscvrt.dll and mscvr71.dll. First one came from Gammu and second one from Python. Starting with 1.19.0, Gammu is built with mscvr71.dll and random crashes are gone. Any tester did not report problems with Windows binary, so I decided to make it finally an official release.
So after year or more Windows users can finally use up to date Wammu version! Fortunately I can produce this version without even touching Windows. Thanks to tools such as MinGW and Wine, everything from compiling to generating installer can be scripted and done automatically on Linux!
So Windows users can now also download current version from http://wammu.eu/download/, enjoy it.
