Thanks, as it's rather small, I simply paste it below. If you need more details you have to tell me how to do that. So basically I get a file from my remote server but it even crashes before doing anything at all. Yesterday, I've played all day with different link details etc. in Eclipse/mingw on Win8 without success. It simply works fine in VC11, Linux, Mac. Many thanks for your help. -------- C:\Users\Michael\Desktop\X-Plane 10 Demo>gdb X-Plane.exe GNU gdb (GDB) Copyright 2010 Free Software Foundation, Inc.

What libcurl version and what libcurl options are you using? Can you show us a full (smallish) program that repeats the problem? How far does the request reach/go before the crash? CURLOPT_VERBOSE may offer some additional clues. segfault in windows? I didn't know you could get that. Can't you run the code with a debugger and see where it crashes? -- /
