Subject: [OMPI users] SIGSEGV in opal_hwlock152_hwlock_bitmap_or.A // Bug in 'hwlock" ?
From: Paul Kapinos (kapinos_at_[hidden])

Hello all,

using 1.7.x (1.7.2 and 1.7.3 tested), we get SIGSEGV from somewhere in-deepth of
'hwlock' library - see the attached screenshot.

Because the error is strongly aligned to just one single node, which in turn is
kinda special one (see output of 'lstopo -'), it smells like an error in the
'hwlock' library.

Is there a way to disable hwlock or to debug it in somehow way?
(besides to build a debug version of hwlock and OpenMPI)
