Crash when using CURLOPT_WILDCARDMATCH

From: Antoine via curl-library <curl-library_at_cool.haxx.se>
Date: Thu, 20 Feb 2020 14:25:47 +0000

Hi,
I'm getting a constant crash with libcurl when using the
CURLOPT_WILDCARDMATCH option. From what I could investigate it crashes in
the following function in ftp.c :
        static CURLcode wc_statemach(struct connectdata *conn)
It crashes on the call to the chunk_bgn callback:
userresponse = conn->data->set.chunk_bgn(
        finfo, wildcard->customptr, (int)wildcard->filelist.size);

It wasn't crashing in our previous versions using libcurl 7.41.0, but it
now crashes constantly with version 7.64.1, although we haven't changed
the code of our chunk_bgn callback function. Is that a known issue, I
couldn't find any info online about it?

Thanks for your help!

Antoine
