Thank you Alex!
Looks good for libgcc_s.so and libstdc++.so.6
Only it makes me wonder, why the elfdump output for none of the
other (non-gcc-runtime-)libs prints "[ LAZY ]" the line right
before the lib.
Interesting is, that even 4.9 has none of the libs with "[ LAZY ]".
As having "lazy load" for libs is there to improve startup latency
for binaries/libs, I would like to ask if someone might find an
example with actually printing "[ LAZY ]".
This can be a completely different binary/project but compiled
with enther the g++ 4.9 or the new g++ 5 version. It should print
"[ LAZY ]" for at least one library. Then I would be completely
happy.
Best Regards,
Thomas
