when will __attribute__((constructor)) NOT called

[Adhemerval Zanella]

'.ctor' section was the 'old' way, afaik GCC will now create and emit
entries on 'init_array' section, as for C++ initialization code.

It won't run either by a bug on the loader or if it does not support
it (not the case on glibc).
