macOS crash: objc[58253]: +[__NSPlaceholderDictionary initialize] may have been in progress in another thread when fork() was called.
Latest lftp stops working on connect with the following error:
objc[58253]: +[__NSPlaceholderDictionary initialize] may have been in progress in another thread when fork() was called.
objc[58253]: +[__NSPlaceholderDictionary initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.
Version 4.9.2 Libraries used: idn2 2.3.0, libiconv 1.11, OpenSSL 1.1.1k 25 Mar 2021, Readline 8.1, zlib 1.2.11
macOS 10.14.6
Installed via Homebrew, also tried recompiling but got the same results.
This is quite strange error as lftp does not use threads at all.

I am having the same problem...

I found a workaround...
export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES
before calling lftp prevents the crash.
