mpmath: mpmath creates Memory Error on import

I wasn’t able to determine the reason, but it seems that when importing mpmath with gmp=6.2.0 it creates a Memory Error during this operation:

mpmath/mpmath/libmp/libelefun.py

# ~= next power of two + 20
cache_prec_steps = [22,22]
for k in xrange(1, bitcount(LOG_TAYLOR_PREC)+1):
cache_prec_steps += [min(2**k,LOG_TAYLOR_PREC)+20] * 2**(k-1)

When I downgraded gmp<=6.1.2.

mpmath imported successfully.

Stack trace is unavailable. If I am able to reproduce behavior I will attach.

python 3.7.6 gmpy2 2.1.0b1
