This is a usually an easy question to answer, however your dependency is
a new twist.

Almost always, a transient build failure like that is a HW problem if
continuing the build "works", in the sense that the same file/module will
build and then another sig 11 will happen (unpredictably) down the road.

However, there is always some finite possibility of a SW or FW issue.

Is the behavior sufficiently reproducible to verify your stated dependency?
That is, is the MTBF << time_spent(testing 1.4T)??
