Internal Compiler Error V14

I am experiencing numerous internal compiler (V14) errors on a largish solution (13 projects, 750 files) that used to compile fine on earlier versions of the compiler. I have not yet updated to V15 to see if the error has been fixed. In an attempt to locate the compiler errors, I narrowed it down to a few lines.

*** the conditional compile as listed below produces an error but does not crash. This may be of interest in diagnosing the problem. Flipping the conditional the other way around produces the ICE.

#if 0
! { compiler bug hunt
    pFiniteSolutionYMM.rBeadIPIF(1,BeadNumber).v = pFiniteSolutionYMM.rBeadIPIF(1,0).v + DUMRUI(1).v
    pFiniteSolutionYMM.rBeadIPIF(2,BeadNumber).v = pFiniteSolutionYMM.rBeadIPIF(2,0).v + DUMRUI(2).v
    pFiniteSolutionYMM.rBeadIPIF(3,BeadNumber).v = pFiniteSolutionYMM.rBeadIPIF(3,0).v + DUMRUI(3).v
#else
    pFiniteSolutionYMM.rBeadIPIF(1:3,BeadNumber).v = pFiniteSolutionYMM.rBeadIPIF(1:3,0).v + DUMRUI(1:3).v

Where

    ! AVX four-up double vector
    type TypeYMM
        SEQUENCE
        real(8) :: v(0:3)
    end type TypeYMM

Due to the size of the solution, I cannot provide a simple reproducer.
