------- Additional Comments From bangerth at dealii dot org 2004-11-25 19:19 ------- I am not an expert in ABI questions, but in my naive world constructors are somewhat different than regular functions if they are declared inline (and synthesized constructors always are): - you can't take the address of a constructor - (old) code linked against a new libstdc++ with a new constructor would be fine since the old synthesized constructor had been inlined - (new) code linked against an old libstdc++ without the new constructor would also be fine if the new constructor were declared inline, since then no call to the respective library function would be attempted IOW, the result is a situation where programs couldn't tell the difference. The fact that you can't take the address of a constructor makes the situation markedly different from the case of a regular function. W.
