Description
Users of the R bindings are getting segfaults in ftp downloads after MacOS updated from libcurl 8.4.0 to libcurl 8.6.0.
We have observed the problem also in libcurl 7.8.1 but not yet been able to narrow it down to a smaller reproducer. It happens when the FTP download is performed in a multi-handle that already performed previous requests (possibly http/2) which seem to have corrupted the multi-handle, making it crash in the ftp download.
I will try to investigate more later, but wanted to open this now in case other people have observed similar issues.
curl/libcurl version
libcurl 8.7.1
