Hendrik,

I've been unable, after 30 successive executions on Windows, to crash
any of your test programs. But there's still some hope ;-) Please
answer all the following...

Have you built libcurl or downloaded from somewhere? If downloaded
provide link to it.

Are you linking your test program against a dynamic (.dll) or static
(.lib)libcurl library?

Which C run-time versions are you using for the library? And for the
test program? Not mixing debug version and release versions?

Have you read "Building Windows DLLs and C run-time (CRT) linkage
issues" in docs/INSTALL ?
