Segmentation fault on unrelated Python exceptions #87
Description
I'd like to use pyosmium using Python 3.6.2. When running the following example code (based on https://github.com/osmcode/pyosmium/blob/master/examples/osm_file_stats.py ) using Python 3, I get a Segmentation fault (core dumped) message (caused by the last line of code) with no additional info. However, running the same code using Python 2.7.15+, gives me a proper error message.
My question is not about this specific example, but about the combination of python3 and pyosmium in general: How would I debug such errors (and why aren't any proper error messages displayed)?
import osmium as o
import sys
class FileStatsHandler(o.SimpleHandler):
def __init__(self):
super(FileStatsHandler, self).__init__()
self.nodes = 0
def node(self, n):
self.nodes += 1
if __name__ == '__main__':
if len(sys.argv) != 2:
print("Usage: python osm_file_stats.py <osmfile>")
sys.exit(-1)
h = FileStatsHandler()
h.apply_file(sys.argv[1])
print("Nodes: %d" % h.nodes)
print("Nodes: " + h.nodes) # XXX: h.nodes should be str(h.nodes)
