Description
If you define a large array of chars (100K) as part of a structure you cannot see it or any of the other parts of the structure. CBuilder 6 has no such limitations and when you push the array size to preclude inspection the other parts of the structure are displayed in the inspection window.
Steps to Reproduce:
New project. Then add this:

#define ARRAY_SIZE 10000

typedef struct
{

int JustAnInt;

bool JustABool;

unsigned char TxBuffer[ARRAY_SIZE];
}TestStruct;

static TestStruct MyStruct;

.....then initialise the array:

int Count;
time_t seconds;
time(&seconds);
srand((unsigned int) seconds);
MyStruct.JustAnInt = rand();
MyStruct.JustABool = (bool)rand();
for(Count=0;Count<ARRAY_SIZE;Count++)
{
   MyStruct.TxBuffer[Count] = (unsigned char)rand();
}

After initialisation Debug->Inspect the structure. All is visible. Now increase the array size and repeat

#define ARRAY_SIZE 10000

The values are no longer visible. CBuilder 6 does not have this limitation.

XE and CB6 projects to illustrate this are attached.

Could you please attach sample project to reproduce/verify your issue?
