It works with vsftpd and a 10-year old version of Pure FTP that I thought would give me a baseline for testing. But my end user has a server I cannot get that exhibits the problem.

It's fundamentally because libcurl will only create missing directories if MULTICWD is set. I switch back to NOCWD because it's very hard if not impossible for me to know where libcurl is in the directory hierarchy when I need to do a QUOTE command, and there would have to be some tricky path manipulation if I did.

I cannot write a test case because it depends on the server. I suspect that it has to do with the format of PWD output that comes right after login.

Note that I switched e-mail addresses to get rid of the legalese my company tacks on.
