From c36b20b7dc2e787f7285e459851df1a74368e8e3 Mon Sep 17 00:00:00 2001 From: Vasant Hegde Date: Wed, 20 Sep 2017 16:52:35 +0530 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.
