Looks like we may just have finally crept up to the limits: standard timeout for any job on travis-ci.org is 50 mins, and the timeout failures I’ve seen all are in the 48+ mins range. Maybe we just have to split our jobs into smaller pieces or remove some tests from the Travis part.
@abadams : waaay back in 2015, you disabled Travis builds of CMake with HALIDE_SHARED_LIBRARY=0 with the comment "Don't build as a static library with cmake. It risks exceeding the travis memory limit.” — any idea why this was happening? Not sure I see what CMake-with-static-library would be more memory-intensive than Make-with-static-library.
