> The best hypothesis I have goes as follows (this was heavily AI assisted): > > We had a similar problem with the ODR violation, but the cause is different here (latest xsimd has the ODR fix). The issue arise during LTO where the fags `-msve-vector-bits=128` and `-msve-vector-bits=256` get conflated, resulting in the 256 version making 128 bits assumptions. We should find out why. Can we enable `CMAKE_VERBOSE_MAKEFILE` on the manylinux build to see all the compiler options for each file? Normally only one `-msve-vector-bits` is passed for each compilation unit. -- This is an automated message from the Apache Git Service.
