      A binary I made with dynamic linking consistently fails with:

      memory allocation/deallocation mismatch at 0x7ffff3569020: allocated with malloc being deallocated with delete []

      The link line for this binary was as follows:

      Crucially, do_debug_malloc_or_debug_cpp_alloc calls

      void* p = DebugAllocate(size, MallocBlock::kMallocType);

      MallocBlock::kMallocType is saved into the allocated block as the alloc_type_. During deallocation, MallocBlock::kMallocType's AllocName, "free", is compared with the DeallocName of the freeing function. "free" is not the freeing function being used, so the deallocation explodes.

      This suggests that do_debug_malloc_or_debug_cpp_alloc is the wrong function to have been called. It's called by tc_malloc. There is another function called tc_newarray, which calls

      void* ptr = debug_cpp_alloc(size, MallocBlock::kArrayNewType, false);

      It has a DeallocName of

      (gdb) p DeallocName(MallocBlock::kArrayNewType)
      $68 = 0x7ffff5d2f31a "delete []"

      which suggests that was the correct allocation function to have been called.
