 *** caught segfault ***
address 0xd8, cause 'memory not mapped'

Traceback:
 1: decompose.graph(sc.gr, mode = "strong")
 2: system.time(sc.comp <- decompose.graph(sc.gr, mode = "strong"))

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection: 3
