How long ago was this, Bulat? I'd be interested to know if any of the compilers since 6.8.x, with all its inlining improvements, exhibited the same fragility.
If I recall correctly, your experiments were around the 6.4.x series of compilers?
yes, exactly. not tried with anything newer, so can't say anything about it -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
