[asan] FuseGPUThreadLoops heap-use-after-free in ExtractSharedAndHeapAllocations #8482

Closed derek-gerstmann closed 1 day ago

derek-gerstmann commented 2 days ago

Discovered this testing main under address sanitizer. It's reproduceable on opencl, vulkan, etc:

I built Halide using the buildbot LLVM v18.1.8 binaries, and the ASAN toolchain:
