c++ - Segmentation fault outside of main -

i'm working on large, mixed c++/fortran project. currently, executable segfaults on startup, before reaching main, afaict. in fact before loading shared libraries.

some output:

as can see, depends on fair number of libraries crashes before ld gets load of them. i'm not sure next. suggestions?

this caused compiling object files -fpic , executable -shared.
