I used a function and get the following results.
int
myvalign(int x) {
return x & pageMask;
}
int argToAlign = oldLimit - heap + delta;
int align = myvalign(argToAlign);
int newSize= min(align, heapLimit);
int newDelta= newSize - heapSize;
oldLimit=0x7929cfe8
delta=0
newSize=23293952
newDelta=-4096
align=23293952
argToAlign=23298024
heap=2009485312
heapLimit=1073741824
