Thanks Dirk. I tried with your line and it works for me too. So I tried shortening it and this works: CXXFLAGS= -std=c++0x -g -O3 but this does not: CXXFLAGS= -std=c++0x -g This also does not work: CXXFLAGS= -std=c++0x -g -Wall -pipe -pedantic -Wno-variadic-macros And neither does this: CXXFLAGS= -g -Wall -pipe -pedantic -Wno-variadic-macros I.e. c++0x was a red herring, and the lack of -O3 is the problem. It works with -O3, -O2, -O1 and -Os, but fails to work with -O0. Very curious. I considered trying each of the individual optimization flags [1], to narrow it down further, until I realized how many of them there were.
