The MCAL IPC library goes into the ASIL-D MCU R5F core. Customer is using GHS Safety Certified Compiler which generates a number of errors and warnings, which do not show up with TI ARM Clang Compiler.

Analysis
GHS doesn't like any structure or variable that has zero size. Given that this is data generated by TI, Customer insists TI fix the issues.
