R help - Feb 2011 - Error: address 0x6951c20, cause 'memory not mapped'

Dear R list,


I get a strange error in R:

 *** caught segfault ***
address 0x6951c20, cause 'memory not mapped'

Traceback:
 1: .C("spline_eval", z$method, nu = as.integer(n), x =
as.double(xout),     y = double(n), z$n, z$x, z$y, z$b, z$c, z$d, PACKAGE =
"stats")
 2: spline(gam.data$x[, col.data], gam.smooths.all$fit[, m], xout =
gam.results.global[m,     , "x.values"], ties = mean)
 3: eval.with.vis(expr, envir, enclos)
 4: eval.with.vis(ei, envir)
 5: source(file.path(getwd(), "Skripte", "r",
"GAM_hourly", "1_calcs_GAM_all_sites_hourly.R"),     echo =
TRUE, max.deparse.length = 2e+05)

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace



It seems as whether the error occurs when I try to perform a spline
interpolation of a smooth function. Can anybody give me some hints on where to
dig for a solution?

Thanks a lot
Jannis

Upgrade to a recent release, and if the error still occurs, try to 
isolate it to a simple reproducible example.
