R-devel,
I discovered a segfault in my R code that boiled down to my incorrect
use of the Recall() function embedded within a with() function. Since
segfaults are generally bad things, even when it's the user's fault for
writing nonsense code, I thought I'd pass along the offending code. I've
tested the crash on R 2.11.1 (on Linux and Mac), but not in devel
versions of R.
Thanks for posting that. It does still exist on R-devel, and as you
say, it shouldn't. I'll fix it.
