[Rcpp-devel] simple patch to fix stack overflow in RInside v. 2011-12-06 23:47:21

[Dirk Eddelbuettel]

Hi John,

I am CC'ing this back to the rcpp-devel list where all RInside comments
should go too.  Could you follow-up on list as well? (Subscriptions needed to
post; else use gmane or nabble to post via web.)

I test them all pre-release on on XP 32bit and they worked for me.  What is

I'll take another look when I am back in the office.  And maybe we could use
strnprintf followed by Rprintf here...

On which platforms are you seeing issues?
