We've solved this bug and it is not OMPI-related.
The long story:
Whenever an .l-file is newer than its corresponding .c-file, it
is generated by a rule from our toplevel Makefile.
svn changes the c/m-time, so flex is called, and probably due to
disabled autoconf-tools, this call is done with wrong parameters.
The question why this behaviour was only seen on some of my
hosts is even weirder: The svn checkout generates timestamps.
If you checkout to an ext2/ext3-filesystem, everything works,
but the failing hosts all use xfs.
We believe that xfs has a higher resolution for timestamps,
so the age of corresponding .l- and .c-files differ for
some value of a very small delta, thus forcing to rerun
flex and breaking the code.
Our fix is quite simple: we touch the .c-files whenever there
are .c-files belonging to existing .l-files. Obviously, the
c-files are now "newer" and regeneration is prevented.
Sorry for inconvenience.
