G++ exhausted the memory while compiling Acceptor.cpp about wangle HOT 6 CLOSED

How much memory did it use?

@djwatson It will use up all my 16GB memory and get killed by the kernel while compiling this file.

I see ~1.5G taken for compilation, although that's on 4.8 or 5. I'm guessing this is a gcc bug, but I'll leave this open until we know for sure.

Also compiles fine with clang 3.9.0

I have frequently built wangle and fbthrift and folly with GCC 4.8 on a 1.5GB VM. Only fbthrift gets close to running out of memory. I would guess that the new GCC is leaky or has an overly expensive optimization pass.

To measure memory usage of a process, you can try /usr/bin/time FAILING COMMAND. Look for maxresident.

The gcc-c++ package from Fedora Rawhide has fixed the problem.

% g++ --version
g++ (GCC) 6.1.1 20160721 (Red Hat 6.1.1-4)
