[Bug 1853826] Re: ELF loader fails to load shared object on ThunderX2 running RHEL7

2019-11-26 Thread Assad Hashmi
For info, a similar type of failure has been seen when loading libarmflang.so on DynamoRIO: https://github.com/DynamoRIO/dynamorio/issues/3385 It's to do with the .dynstr section being mapped incorrectly causing a SIGBUS. ** Bug watch added: github.com/DynamoRIO/dynamorio/issues #3385
