Re: malloc and memcpy

typedef struct FPARRAY{
    unsigned short iRows,
         iCols;
    double dArray[FPARRAY_SIZE];
} FPARRAY;

__declspec(dllexport) double initialize(LPFP st, LPFP h, LPFP ffd,
LPFP bt, int hr, int it, int ic)
{
    swap_table = (LPFP)malloc(sizeof(FPARRAY));
    memcpy(swap_table, st, sizeof(FPARRAY));
    holidays = (LPFP)malloc(sizeof(FPARRAY));
    memcpy(holidays, h, sizeof(FPARRAY));
    futurefrontdate = (LPFP)malloc(sizeof(FPARRAY));
    memcpy(futurefrontdate, ffd, sizeof(FPARRAY));
    blend_table = (LPFP)malloc(sizeof(FPARRAY));
    memcpy(blend_table, bt, sizeof(FPARRAY));
    holiday_rule = hr;
    int_tech = it;
    int_curve = ic;
}

so essentially i wrote a dll, and I can get excel to pass to me these
things called FPARRAY structures. I comment a few of the malloc and
memcpy and the function is able to run a few times before crashing. i
am not exactly sure whats going
