Segmentation fault in Measured Block State under Debian 10 Buster

Hi, I am using graph_tool version 2.37 (commit 1d377b3e) installed from the package manager, on a server with Debian 10 Buster and python 3.7.3. Whenever I try to copy (or sometimes instantiate) a MeasuredBlockState, I get segmentation fault.

Here is an example:

from graph_tool.all import *

g = collection.data["lesmis"].copy()

n = g.new_ep("int", 2)
x = g.new_ep("int", 2)

state = MeasuredBlockState(g, n = n, x = x, n_default = 0, x_default = 0)

st = state.copy()

This situation does not happen with neither Uncertain nor MixedMeasured states on Debian.

Also, I migrated a stalled box to Ubuntu 20.4 focal and everything goes fine.

Thank you. Herlander
