If at least -O1 is given then the client crashes on startup without disabling this optimisation. It is supported at least since GCC 3.4. This was a tricky one to find because -O0 works and -O1 doesn't but the GCC manual says this optimisation is only enabled at -O2. Turns out it is also enabled by default on most targets. It may be possible to narrow it down to a specific subproject or source file but applying it globally seems safest.
