I am getting below warning and compilation stops, kindly help.

```auto
DEBUG: Executing shell function do_compile_ptest_base
# github.com/mendersoftware/mender/vendor/github.com/bmatsuo/lmdb-go/lmdb
mdb.c: In function 'mdb_cursor_put':
mdb.c:6535:9: warning: this statement may fall through [-Wimplicit-fallthrough=]
      if (SIZELEFT(fp) < offset) {
         ^
mdb.c:6540:5: note: here
     case MDB_CURRENT:
     ^~~~

```

This is just a compile time warning and should not cause the compilation to stop. If you can share more of the log, I am sure there is something else at play here

Also, what branch of Yocto are you building and what distro and version is your build host?

And the thing is my colleagues don’t see this issue for same project and on same machine.

There must be something else in the log file `log.do_compile_ptest_base.32204`. As @mirza mentioned the above message is just a warning and should not stop the build.

Yeah, that is what I’m not understanding, if I open log which it mentioned it same again.
