    Description

      The RLP library has various memory errors that tcmalloc detects in debug builds. When TCMalloc detects an error it will log the error, and call abort() while holding a spinlock. Our abort handler prints stack traces by calling backtrace() and this function needs to allocate memory on most architectures. This memory allocation will thus cause a deadlock in the spinlock since the spinlock is not recursive.
