I am using 2.c and the command from comment #8 to compile lib2.so; my
assumption is: if .bss section is coming from other source files it should not
change it's size if I initialize one of global ints to some non-zero value; but
if I do .bss section size drops from 8 to 4 bytes as expected and data section
increases by 4 bytes. So it looks like .bss section is allocated for the global
variables declared in 2.c. Am I missing something else here?
