Type of Bug

Compile-time Error

Component

CUB

Describe the bug

CUB inconsistently invokes _CubLog without surrounding #ifdef CUB_DETAIL_DEBUG_ENABLE_LOG in CachingDeviceAllocator. This leads to issues with printf. GCC 13 seems to have removed stdio from some of its headers, so this issue was unmasked. nvbug 4402427

How to Reproduce

#include <cub/util_allocator.cuh>

int main() {}

When compiled with GCC 13:

nvcc -ccbin=g++-13.2 main.cu
cccl/cub/cub/util_allocator.cuh(386): error: identifier "printf" is undefined
if (debug) do { { printf("Changing max_cached_bytes (%lld -> %lld)\n", (long long) this->max_cached_bytes, (long long) max_cached_bytes_); }; } while (false);

Expected behavior

Successful compilation
