No, I have tried to compile git develop branch with your flags and it
succeeded without errors. As I said, I have gcc 4.8.2 on Ubuntu. I'm not
sure how to verify that LTO was actually used. The object files (*.o) have
the !__gnu_lto_v1 symbol, if that's an indication. OTOH, objdump produces
disassembly for these files, which I find surprising.
> Disabling LTO fixes the issue, sorry I forgot to mention that in my
initial bug report. I guess this bug should be reported upstream to the
GCC devs? Can you do this or do I have to deal with it? I'm wondering why
I haven't found any other guys around who fail to compile boost >=1.54
with LTO enabled.
I suppose, LTO is not used very often yet in Linux world. Since I cannot
reproduce the failure, it's probably easier for you to communicate with
gcc devs (or package maintainers in Gentoo) regarding this issue.
