We've seen situations where Linux and Mac test builds crash while linking tests. The
large number of Qt-based test executables (43) all trying to link at the same time
can provoke out-of-memory conditions on Linux, triggering the OOM killer and build
errors like:
collect2: fatal error: ld terminated with signal 9 [Killed]
On Mac, the simultaneous Qt loads can provoke a linker crash with symptoms like:
c++: c++: error: unable to execute command: Bus error: 10
c++c++: error: linker command failed due to signal (use -v to see invocation)
Also, there appears to be a multiple load of GoogleTest, because the existing code
references both GTest::gtest and GTest::gtest_main; provoking messages like:
ld: warning: ignoring duplicate libraries: '/Users/lunarg/.jenkins/vt0/Debug64/VulkanTools/external/googletest/build/install/lib/libgtest.a'
Removing the reference to GTest::gtest removes the redundant reference.

There's something wrong with dependency management here. Closing until I can figure it out. |
