Research direction

Start with src/tbb/tools_api/ittnotify_static.c at line 231 and the sanitizer traces for libtbbmalloc.so.2 and libtbb.so.2. Investigate why both libraries register __itt__ittapi_global when loaded together under CRAN's GCC sanitizer environment. Done means the reported ODR violation no longer occurs in that environment.

Written by the indexing model from the issue text.

Description

I am getting the following ODR violation; CRAN asked me to fix ODR violations in my package, and this one came up:

==136164==ERROR: AddressSanitizer: odr-violation (0x7efd2f2f1240):
  [1] size=168 '__itt__ittapi_global' ../../src/tbb/tools_api/ittnotify_static.c:231:14
  [2] size=168 '__itt__ittapi_global' ../../src/tbb/tools_api/ittnotify_static.c:231:14
These globals were registered at these points:
