Description iosipos.mpekenmpaouer 2017-10-24 19:21:36 UTC 
When the hashtable size (nnodes) reaches 2^29 an integer overflow occurs in function g_hash_table_maybe_resize so that condition "size > hash_table->nnodes * 4" becomes true and g_hash_table_resize is called, requesting an absurd size of memory. e.g.:

GLib-ERROR **: /build/glib2.0-y6934K/glib2.0-2.42.1/./glib/gmem.c:353: overflow allocating 18446744071562067968*8 bytes
