what could cause a C++ program to have some bugs when compiled by someone else ?
eintemporel's builds of noggit red have some issues with what I believe to be wrongly initialised variables, if I build it I don't have any of those bugs.
Could like a compiler default integers to 0(mine) and another to some random value ?

if so would defaulting all the values in the header files fix it for all compilers ?

In debug all variables are usually auto intialized

If something behaves differently under different compilers or release vs debug, that means there is undefined behavior in the code somewhere
