Please note that ffmpeg is constantly printing to screen (vga or serial 
console?) some output about progress.

Once connected to gdb I see this stacktrace:

I wonder if this is related 
to https://github.com/cloudius-systems/osv/issues/1010 (though no 
httpserver at all) and 
this https://github.com/cloudius-systems/osv/issues/536.

Please note that the common thing between all these stack traces is 
fmt_fp() function in libc/stdio/vfprintf.c:300. Coincidence?
