[Rcpp-devel] Possible regression in R-3.2.3 or Rcpp 0.12.3

[Dirk Eddelbuettel]

Paul,

I can reproduce the segfault on Ubuntu 15.10, "everything current".
Definitely a valid bug report, though a 30mb xlsx may not qualify as
minimal.

I won't have time to look at this for a while though so if you find that
downgrading helps that may be your best bet.

Thanks for the report.  I am so used to simple segfaults from ABI mixings
(g++-5.* will do that for you...) that I called this wrongly at first. 

Dirk
