Please describe the problem.
NB can't change the title since it is not about depends since libgcc-s1 is essential... so most likely some LD_LIBRARY_PATH manipulation is in place or smth like that.

or may be that is an issue with rclone? in this case it was

I have tried to reproduce locally with exactly those installations of rclone and git-annex but not getting the same problem 
I have also ran with --debug and got

Any ideas Joey?
I'm a bit surprised git-annex is using
pthread_cancel, sincestringsdoes not show it contains that symbol. Perhaps one of the other pthread symbols it uses ends up calling that.It does seem though from the message that it's git-annex and not a program it runs that is core dumping on this. Also I checked, and the rclone you installed is a statically linked binary so I would not expect it to use
libgcc_s.so. And And git-annex-remote-rclone is a bash script, and bash doesn't use pthreads.(I do think that, in general, using the git-annex standalone tarball and then trying to run additional programs besides git-annex inside it is not going to always work well. Standalone interposes its own versions of libraries, which may not work with the other programs. There is already a todo about that, ?strong>.)
I've added
libgcc_s.so.1to the standalone build.
