I'm quite sure you can reproduce the p= roblem on a fresh Ubuntu 14.04 with the following =2E/autogen.sh ; ./configure --disable-static --with-debug CFLAGS=3D"-Wal= l -g" CXXFLAGS=3D"-Wall -g" it fails consistently in my container. When I try with ./configure it doe= s not fail. Something is going on when there is -g instead of the default= flags. I checked that --disable-static and --with-debug make no differen= ce.
