Missing lib leads to SIGSEGV
Hi,
I've got Segmentation fault while performing scan in python client. The reason was that I had not installed pybloom lib on the machine where I was performing the scan, but I had some pybloom objects stored in the DB. I get that the code should fail but it should raise some resonable Exception. I had to find the problem with strace.
If I will have some spare time I will try to improve that. I think that the code below is responsible for that and should be wrapped somehow: https://github.com/aerospike/aerospike-client-python/blob/master/src/main/scan/foreach.c#L61
strace output:
