From: Ingo Müller <<bugzilla.monetdb.org>>

I am trying to compile the Mar2018_SP1_release branch like so:

./bootstrap && rm -rf build && mkdir build && cd build && CC=gcc-8.1 ../configure --enable-debug=no && make

With:

$ gcc-8.1 --version
gcc-8.1 (GCC) 8.1.0

But fail with the following error:

(A similar error repeats a couple of times more.)

Compiling with --enable-debug=yes (or no option set) works fine. The only difference in the failing command is "-O2" (and the commands succeed/fail if I manually remove/add that option). Compiling with clang 5.0 works fine with an otherwise unchanged setup.

Configure using --disable-strict and it will compile (although you will get warnings).

This is actually fixed in the default branch. I don't think this will be fixed in the Mar2018 branch since there are too many changes for a release branch.
