Address 0x7f5ec046d420 is located in stack of thread T0 at offset 32 in frame

    #0 0xc1b3af in getOCLTypeName(llvm::Type*, bool) /mnt/b/sanitizer-buildbot3/sanitizer-x86_64-linux-fast/build/llvm/lib/Target/AMDGPU/AMDGPUAsmPrinter.cpp:798
  
  This frame has 6 object(s):
    [32, 56) 'ref.tmp' <== Memory access at offset 32 is inside this variable
    [96, 120) 'ref.tmp4'
    [160, 184) 'ref.tmp11'
    [224, 248) 'ref.tmp12'
    [288, 312) 'ref.tmp20'
    [352, 376) 'ref.tmp21'

HINT: this may be a false positive if your program uses some custom stack unwind mechanism or swapcontext

  (longjmp and C++ exceptions *are* supported)
