Infeasible problems cause R to crash

[travis-leith]

R version 4.2.1 (2022-06-23 ucrt) -- "Funny-Looking Kid"
Package osqp version 0.6.0.5

When I run the following infeasible problem, R crashes.

rm(list = ls())

library(osqp)
## example, adapted from OSQP documentation
library(Matrix)

P <- Matrix(c(11., 0.,
              0., 0.), 2, 2, sparse = TRUE)
q <- c(3., 4.)
A <- Matrix(c(-1., 0., -1., 2., 3.,
              0., -1., -3., 5., 4.)
            , 5, 2, sparse = TRUE)
u <- c(0., 0., -15., 100., 80)
l <- u + 1

settings <- osqpSettings(verbose = TRUE)

# Solve with OSQP
res <- solve_osqp(P, q, A, l, u, settings)
res$x

Ah, I do confirm this on osqp 0.6.0.7 as well. (My initial reply was wrong.)

This problem still exists with R4.2.2. Would be awesome if we could get it fixed.

problem still exists with R4.3.0

If I had the skills to fix this, would love to. Sadly, I do not know enough about c++

I'm closing this issue as addressed in version 0.6.3 with a check at the R side. So an error will be thrown rather than a crash.
