发帖数: 4933 | 1 Hi,
I am trying to write a program on mac. The program works on
PC, however, when I run it on Mac, some weird things happen.
The values of some variables keep changing. I suspect there
are at least two things related: memory allocation and
double precision. But I monitored all the memory allocation,
there are no error reported. For some double precision
variables, the values does change, but not all the
variables. I didn't use any mac toolbox or any specific
functions, and all the codes are in | f****n

know, for auto variables, they are generated dynamically. maybe
your PC compiler gives these variable a default value(probably 0)
while your Mac compiler does not.
