The customer who continually experiences the problem contacted "the curator" only to be told that the problem might have something to do with the quality of the code generated by the gcc compiler. Huh?

That feels more like a system spinlock problem or somebody decided to "write their own".  gcc doesn't know from spinlocks.  There are system calls to manage them.  Such bugs are hard to track down on any platform.  We've had them on OpenVMS in the past.  It doesn't appear to be wide-spread since a Google search on several terms didn't find anything.
