在.:: Krig.engine.default中使用的本征函数内部的.Internal(La_rs(x,FALSE))调用导致我的R控制台[1]在一个巨大的脚本被触发之后崩溃.
我相信这是造成爆炸的一线.但是,同一行在新会话中不会崩溃：
x <- structure(c(0.00251355321405019,-0.000589785531216647,-0.000172411748626129,-0.000589785531217227,0.000897505637785858,-0.000714600035538855,-0.000172411748626269,-0.000714600035538766,0.00123946691634644),.Dim = c(3L,3L)) .Internal(La_rs(x,FALSE))
您可以使用以下三行重现此控制台崩溃(大约十分钟)：
# install.packages( c("MonetDB.R","MonetDBLite","survey","SAScii","descr","downloader","digest","sas7bdat","R.utils","ggplot2","scales","mapproj","sqldf","maptools","raster","rgeos","stringr","plyr","mgcv","spatstat","rgeos"),repos=c("http://dev.monetdb.org/Assets/R/","http://cran.rstudio.com/"))

对不起,这个例子不是最小的,当我删除不同的东西时,崩溃消失了
2016年2月22日编辑：更糟糕的是,当我尝试一个脚本来自行触发崩溃,它不会死！

谢谢！

如果我一次运行整个脚本,R在Rterm.exe中没有任何信息崩溃.但是如果我将脚本分成两部分,R给我这个错误：

更多的调试信息：它看起来像.Internal()函数La_rs已经被破坏了吗？

2016年2月21日更新：我能够在第二个Windows脚本上重现此错误(无R死亡).这里是永久链接

这里是错误发生了什么. La_rs再次出现损坏.
