I'm seeing some warnings when building 1.4.2rc1 that should probably be addressed before release:
runtime/opal_params.c: In function opal_register_params:
runtime/opal_params.c:39: warning: unused variable ret
coll_tuned_module.c: In function tuned_module_enable:
coll_tuned_module.c:194: warning: unused variable i
rcache_vma.c: In function mca_rcache_vma_module_init:
rcache_vma.c:41: warning: assignment from incompatible pointer type
The first two are trivial and I will simply fix them myself. The last one is less obvious to me - can someone with knowledge of that code give us a patch?
