I've been there too. The clang compiler does useful validation and
troubleshooting of your code in addition to what you get with gcc. I
recommend installing/trying it as a complement to your default setup.
It has a -c option for "Only run preprocess, compile, and assemble
steps" allowing you do check you code as:
clang -c -pedantic -Wall -I$(R_HOME)/include/ src/*.c
I wouldn't be surprised if this would be enough for you to identify
and fix the problematic code.
Hope this helps
