Sometime relatively recently, this note started showing up in build of hotspot:

../src/share/vm/jvmci/jvmciCompilerToVM.cpp: In static member function 'static objArrayHandle CompilerToVM::initialize_intrinsics(Thread*)':
../src/share/vm/jvmci/jvmciCompilerToVM.cpp:206:16: note: variable tracking size limit exceeded with -fvar-tracking-assignments, retrying without
 objArrayHandle CompilerToVM::initialize_intrinsics(TRAPS) {

It's just a note, so doesn't stop the build, but it's annoying clutter in the build log, and slows down the build ever so slightly.
