Could you try the latest 3.0.0b2 version?

[rossengeorgiev]

@xfxyjwf, 3.0.0b2 compiles.

$ uname -sorvm
CYGWIN_NT-10.0 2.2.0(0.289/5/3) 2015-08-03 12:51 x86_64 Cygwin
$ ./src/protoc.exe --version
libprotoc 3.0.0

However, make check fails.

We're seeing what I think is this same error on Fedora Rawhide with 3.1.0. gdb shows:

I've run into a similar segmentation fault when build protobuf 3.4.1 with a custom GCC 7.2.0. Removing a -O2 optimization flag from CXXFLAGS fixed the segmentation fault. Setting the same optimization flag in the PROTOBUF_OPT_FLAG variable did not effect the test suite.
