As this\r\nis the thread which caused the SEGV in the first place, it made the\r\nsigstack printer less-than-useful.\r\n\r\nWe were not able to identify why it worked with the CLONE_VFORK in\r\nsome cases.\r\n\r\nFurther, we observed that instances exiting with SEGV/BUS/ILL always\r\nreturned exit status 134 (SIGABRT).  This rethrows the signal in\r\norder to get the correct exit status.\r\n\r\n(cherry picked from commit 0ad1c49696730150d9115c912de775e6653285e1)\r\n\r\nForward port from 7_4_x"},"comment":{"url":"https://api.github.com/repos/cms-sw/cmssw/issues/comments/133072636","html_url":"https://github.com/cms-sw/cmssw/pull/10886#issuecomment-133072636","issue_url":"https://api.github.com/repos/cms-sw/cmssw/issues/10886","id":133072636,"user":{"login":"cmsbuild","id":4170616,"avatar_url":"https://avatars.githubusercontent.com/u/4170616?v=3","gravatar_id":"","url":"https://api.github.com/users/cmsbuild","html_url":"https://github.com/cmsbuild","followers_url":"https://api.github.com/users/cmsbuild/followers","following_url":"https://api.github.com/users/cmsbuild/following{/other_user}","gists_url":"https://api.github.com/users/cmsbuild/gists{/gist_id}","starred_url":"https://api.github.com/users/cmsbuild/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/cmsbuild/subscriptions","organizations_url":"https://api.github.com/users/cmsbuild/orgs","repos_url":"https://api.github.com/users/cmsbuild/repos","events_url":"https://api.github.com/users/cmsbuild/events{/privacy}","received_events_url":"https://api.github.com/users/cmsbuild/received_events","type":"User","site_admin":false},"created_at":"2015-08-20T16:47:18Z","updated_at":"2015-08-20T16:47:18Z","body":"-1 \nTested at: 3769f741f79686364016b71b751b3198f2101619\n When I ran the RelVals I found an error in the following worklfows: \n 1000.0 step2\n<pre>runTheMatrix-results/1000.0_RunMinBias2011A+RunMinBias2011A+TIER0+SKIMD+HARVESTDfst2+ALCASPLIT/step2_RunMinBias2011A+RunMinBias2011A+TIER0+SKIMD+HARVESTDfst2+ALCASPLIT.log\n\n----- Begin Fatal Exception 20-Aug-2015 17:36:06 CEST-----------------------\n\nAn exception of category 'FallbackFileOpenError' occurred while\n\n   [0] Constructing the EventProcessor\n\n   [1] Constructing input source of type PoolSource\n\n   [2] Calling RootFileSequenceBase::initTheFile()\n\n   [3] Calling StorageFactory::open()\n\n   [4] Calling XrdFile::open()\n\nException Message:\n\nFailed to open the file 'root://xrootd-cms.infn.it//store/data/Run2011A/MinimumBias/RAW/v1/000/165/121/0699429A-B37F-E011-A57A-0019B9F72D71.root'\n\n   Additional Info:\n\n      [a] XrdCl::File::Open(name='root://eoscms//eos/cms/store/data/Run2011A/MinimumBias/RAW/v1/000/165/121/0699429A-B37F-E011-A57A-0019B9F72D71.root?svcClass=default', flags=0x10, permissions=0660) => error '[ERROR] Server responded with an error: [3011] Unable to open file /eos/cms/store/data/Run2011A/MinimumBias/RAW/v1/000/165/121/0699429A-B37F-E011-A57A-0019B9F72D71.root; No such file or directory\n\n' (errno=3011, code=400).
