I can reproduce a crash using the following code:

for (i in 1:100) {
windows()
plot(1:100)
}

When R opens too many graphics windows, it is running out of memory, but not failing gracefully. It should be easy to fix.

The workaround in the short term is not to accumulate open graphics windows; close them when you're done. This code runs without error:

for (i in 1:100) {
windows()
plot(1:100)
dev.off()
}
