Ugh, no, that is way too premature.  This really shouldn't be a dynamic

relocation.  And asan shouldn't be registering the same (common or in the end

non-common) var multiple times from different shared libraries or binaries.



For this we should have a way to refer using non-dynamic relocation to the

common symbol (like R_*_32 or R_*_64, but resolved to the local copy of the

symbol, not global one; or can we have .hidden aliases to common symbols?), and

this size relocation should be also resolved at link time.
