Hello,

When I call (execlp "vim") or (execlp "nano") in Guile :
Fatal error 11: Segmentation fault[1]    31380 segmentation fault  guile test.scm

Guile --version :
guile (GNU Guile) 2.2.3

Vim --version :
VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Apr  4 2017 18:14:54)

Nano --version :
GNU nano version 2.0.6 (compiled 14:26:45, Oct 14 2016)

uname -a :
Darwin e1r5p17.42.fr 16.7.0 Darwin Kernel Version 16.7.0: Thu Jun 15 17:36:27 PDT 2017; root:xnu-3789.70.16~2/RELEASE_X86_64 x86_64

My .guile is empty, I think it's probably a bug with termcaps..
