Incorrect use of _symval causes TI MSP430 v15.12.2.2.LTS internal compiler error

While using MSP430 compiler v15.12.2.2.LTS to create a project for a MSP540F5438 used the _symval in the following call:

    memcpy ((void *) (_symval (RAM_VECTORS_START_SYM)), (void*)(0xFF80), 0x80);

i.e. made a coding error by not taking the address of the linker defined RAM_VECTORS_START_SYM symbol. This caused the compiler to report a warning but then crash with an internal error:

This may be a serious problem.  Please contact customer support with a
description of this problem and a sample of the source files that caused this
INTERNAL ERROR message to appear.

Cannot continue compilation - ABORTING!

The complete CCS 6.1.3 project is attached. MSP430F5xx_6xx_isr_during_flash_ops.zip

When the code was corrected to the following the compiler produced no warnings, no longer crashed and generated the correct code:

    memcpy ((void *) (_symval (&RAM_VECTORS_START_SYM)), (void*)(0xFF80), 0x80);
