Subject: [PATCH 1/3] lsvpd: Add workaround for std::ios_base::failure' issue
Recently on P9 we started seeing below error.
#vpdupdate
terminate called after throwing an instance of 'std::ios_base::failure'
what(): basic_filebuf::underflow error reading the file
Aborted (core dumped)
It turns out that we needed c++ fix. Lets add workaround so that we
don't crash.
