Compiler Error C2356

  • Article

initialization segment must not change during translation unit

Possible causes:

  • #pragma init_seg preceded by segment initialization code

  • #pragma init_seg preceded by another #pragma init_seg

To resolve, move the segment initialization code to the beginning of the module. If multiple areas must be initialized, move them to separate modules.

The following sample generates C2356:

// C2356.cpp
#pragma warning(disable : 4075)

int __cdecl myexit(void (__cdecl *)());
int __cdecl myexit2(void (__cdecl *)());

#pragma init_seg(".mine$m",myexit)
#pragma init_seg(".mine$m",myexit2)   // C2356
