This shows that you have a libcurl build with IPv6 support, and when it tries
to resolve a name using getaddrinfo() it crashes.

This is not a known problem (to me at least).

What glibc version is this? Can you please set a break-point in
Curl_getaddrinfo() and make sure that all the input arguments to
getaddrinfo() looks valid (and possibly show them to us) just before it calls
the failing getaddrinfo?

Of course it all depends what is causing this.

A reasonable work-around might be to rebuild libcurl without IPv6 support, as
then it'll use gethostbyname_r() instead of getaddrinfo()...

Oh yes, that's an old bug that doesn't concern this (the patch there is even
for the gethostbyname_r() usage which your version doesn't use)...
