No it's, not a bug, because the C++ standard says the order is unspecified. The
compiler is allowed to reorder them, and that's what happens with -flto.

Without -flto I can specify link order. So -flto will ignore the order? It is
still a bug as in many cases orders do matter.

In the attached test case, there is a makefile and source code. Here's the
output without -flto:
$ make
g++ -std=c++11 -Wall -g -O2 -o main.o -c main.cpp
g++ -std=c++11 -Wall -g -O2 -o module.o

Hello.
The attached libraries are not what we can use as a reproducer:

Are you sure this just not a divide by zero? On x86, an integer divide by zero
will throw an FPU exception.
