I have a CUDA C/C++ application that I wrote for an RTX2060, which I am now debugging. The first step that I took was to run the executable with compute-sanitizer, and discovered there were some out-of-bounds accesses occurring. Essentially, a very similar issue to the one happening in this thread: Unspecified launch failure on Memcpy. Here is what one looks like:

Starting iteration 0
Evolving fluid interior and boundary
========= Invalid __global__ read of size 4 bytes
=========     at FluidAdvance(float *, float *, float *, float *, float *, float *, float *, float *, const float *, const float *, const float *, const float *, const float *, const float *, const float *, const float *, float *, float *, float *, float *, float *, float *, float *, float *, float, float, float, float, float, int, int, int)+0xfc50
=========     by thread (0,2,0) in block (0,0,0)
=========     Address 0x74fafcffc110 is out of bounds
=========     and is 16,112 bytes before the nearest allocation at 0x74fafd000000 of size 1,048,576 bytes
=========     Saved host backtrace up to driver entry point at kernel launch time

Using my novice understanding of CMake I had a working build system functioning, and in order to determine where the out of bounds accesses are occurring, I added the following line to CMakeLists.txt:

target_compile_options(imhd-debug PRIVATE $<$<COMPILE_LANGUAGE:CUDA>:
                        -v
                        -g
                        -lineinfo
                        >)

However, when I rebuild the project, and run compute-sanitizer, I do not find any information added to the output that indicates the lines in the source where the errors are occurring.

Why is this, and what do I need to do to fix it? Thank you for any help.
