std::bad_alloc

[WithHades]

When I run the plz77_1.exe to compress the data of chr22.dna, the program runs a error:
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

I debug the code and find out the error happend in the rangeMin.cpp:
line 39 to line 41:
parallel_for(intT i=0;i<depth;i++) {
table[i] = new intT[n];
}

when the error is occured, the depth is 21 and the n is 23035842.
I run the code:
int main()
{
int** table = new int*[21];
for (int i = 0; i < 21; i++) {
table[i] = new int[23035842];
}
return 0;
}
it's ok.
So I think this error is related to memory leak, but I checked the code and released the applied objects, the problem is still unresolved.

Can you help me solve this problem?
thx.
