[R] R segfault at startup, causing R crash

[C W]

Dear R list,

Every time I start R, the following error message come up:

 *** caught segfault ***
address 0x0, cause 'unknown'

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:

I am unable to do a sessionInfo(), but I am using:
R version 3.2.4 (2016-03-10)
Platform: x86_64-apple-darwin13.4.0 (64-bit)


I would appreciate any help, thanks so much!
