Runtime failure with illegal instruction fault causing core dump
The main build test was failing with an illegal instruction error when trying to build the g‐2 simulation code on the Fermilab Jenkins build service. The build test attempts to run the simulation for a few events. Of particular importance is the fact that the test fails on older SLF6 build nodes (e.g. buildservice001, 002) but succeeds on newer SLF6 build nodes (e.g. buildservice004, 005).
Also perhaps relevant ‐ on a previous build of the simulation code, g‐2 was seeing illegal instruction errors when trying to run the verification package on the grid. The errors occurred on older worker nodes only.
