I've just encountered a segfault when using DierckxSpline::percur
function. Below is the minimal example which triggers the error:
---
library(DierckxSpline)
x <- 1:10
y <- rep(0, 10)
pspline <- percur(x, y)
---
*** caught segfault ***
address (nil), cause 'memory not mapped'
Traceback:
1: .Fortran("percur", iopt = as.integer(iopt), m = as.integer(m),
x = as.single(x), y = as.single(y), w = as.single(w), k = k, s =
as.single(s), nest = as.integer(nest), n = as.integer(n), knots =
Knots, coef = coef, fp = single(1), wrk = wrk, lwrk = lwrk, iwrk =
iwrk, ier = integer(1))
2: curfitSS(xyw, s = s, knots = knots, n = n, from = From, to = To,
k = k, periodic = periodic, ...)
3: curfit.default(x, periodic = TRUE, ...)
4: curfit(x, periodic = TRUE, ...)
5: percur(x, y)
Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
