trying to debug I notice a strange pattern on ssh search:
1)  ssh is only searched on the PATH directories that end with "bin"
    other directories are skipped.
2) //usr/bin/ssh is not on the PATH but is searched.
   Why and where is defined in the code ?

any idea from where this //usr/bin/ssh is coming for ?

/usr/bin is one of the default posix locations for system binaries, so I would 
expect it is in your path.

/usr/bin        yes
but
//usr/bin       no.

on cygwin "//" is always a network path and "//usr/bin" does not exist.

   34 1808236 [main] orterun 6304 normalize_posix_path: src /usr/bin/ssh

my path is much longer but only the bin directory are searched

   37 1810858 [main] orterun 6304 normalize_posix_path: src //usr/bin/ssh

this is the anomaly


as immediately after the "//" search mpirun crashes

I suspect this search is the culprit.

If someone is interested I put here

all the config, check and make logs plus the ompi_info output.
