Extended Description

I am seeing the following test failures running check-asan on Linux x86_64 (Ubuntu 18.04) with commit 1956cf1042d3c406d9e9cefe47d3b43adf2bdbe1 from earlier today. I guess there is no CI testing of this configuration?

These tests are failing: AddressSanitizer-x86_64-linux :: TestCases/Linux/activation-options.cpp AddressSanitizer-x86_64-linux :: TestCases/Linux/odr-violation.cpp AddressSanitizer-x86_64-linux :: TestCases/Linux/odr-vtable.cpp AddressSanitizer-x86_64-linux :: TestCases/Posix/start-deactivated.cpp AddressSanitizer-x86_64-linux :: TestCases/handle_noreturn_bug.cpp

I've noticed that the situation has changed: e.g. on amd64-pc-solaris2.11 two of those tests XPASS now (and the 64-bit tests don't run since that ASan port is currently 32-bit only):

Unexpectedly Passed Tests (4):
  AddressSanitizer-i386-sunos :: TestCases/Posix/start-deactivated.cpp
  AddressSanitizer-i386-sunos :: TestCases/handle_noreturn_bug.cpp
  AddressSanitizer-i386-sunos-dynamic :: TestCases/Posix/start-deactivated.cpp
  AddressSanitizer-i386-sunos-dynamic :: TestCases/handle_noreturn_bug.cpp

On x86_64-pc-linux-gnu, all 5 tests above XPASS:

Unexpectedly Passed Tests (15):
  AddressSanitizer-i386-linux :: TestCases/Linux/activation-options.cpp
  AddressSanitizer-i386-linux :: TestCases/Linux/odr-violation.cpp
  AddressSanitizer-i386-linux :: TestCases/Linux/odr-vtable.cpp
  AddressSanitizer-i386-linux :: TestCases/Posix/start-deactivated.cpp

  AddressSanitizer-x86_64-linux :: TestCases/Posix/start-deactivated.cpp
  AddressSanitizer-x86_64-linux :: TestCases/handle_noreturn_bug.cpp

but for AddressSanitizer-x86_64-linux-dynamic. Quite ugly to handle in the testsuite, unfortunately.
