---------------------------------------------------------------------
The information in this article applies to:
- The Microsoft C/C++ Compiler (CL.EXE), included with:
Microsoft Visual C++ for Windows, version 1.0 and 1.5
---------------------------------------------------------------------
SYMPTOMS
========
When you build a project containing an initialized huge array, the linker
generates this error message:
L1103: TEST5_DATA : attempt to access data outside segment bounds
TEST is the name of the source file where the initialization occurred.
WORKAROUND
==========
To work around this problem:
- Initialize smaller memory objects, using pointers to reference them (see
the TEST2.C sample below).
-or-
- Initialize the variable members within the executable code.
-or-
- Initialize the variable members within the executable code using a file
to set data values (No sample provided).
STATUS
======
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article. We are researching this problem and will
post new information in the Microsoft Knowledge Base as it becomes
available.
MORE INFORMATION
================
This problem occurs only if an element that is near the 64K boundary of the
array is initialized. In the sample code below, initializing the member
"a[0].b" causes the error to occur:
Sample Code
-----------
*\
The following code sample does reproduce the problem.
// TEST1.C
struct test {
int a[32767];
char b;
};
struct test _huge a[2] = {{{1,2,3},{'a'}}, {{11,12,13},{'b'}}};
void main() {}
The following code samples do not reproduce the problem:
// TEST2.C
int x[32767] = {1,2,3};
int y[32767] = {11,12,13};
struct test {
int *a;
char b;
};
struct test _huge a[2] = {{x,'a'}, {y,'b'}};
void main() {}
// TEST3.C
struct test {
int a[32767];
char b;
};
struct test _huge a[2] = {0}; //Initialization prevents L1072 error
void main() {
a[0].a[0] = 1;
a[0].a[1] = 2;
a[0].a[2] = 3;
a[0].b = 'a';
a[1].a[0] = 11;
a[1].a[1] = 12;
a[1].a[2] = 13;
a[1].b = 'b';
}
