Hi list, 

Please tell me why sometimes RSymphony.dll crashes on
Windows 7 (may be on other Windows too). 

I saw that it depends on
input data. For example this code bring to crash:


library('Rsymphony')
mat = c(0, 1, -100.37967, 0, 0, 1, 0, 0, -200, 0,
0, 1, -0.4, 0, 0, 1, 0, 0, -0.4, 0, 0.5, 0, 0, 0, 0, 0, -1, 0, 0, 0)
mat
= matrix(mat, nrow=6, byrow=TRUE)
mat

dir = c("=", "==", "==")
rhs =
rep(0, 6)
obj = c(1, 1, 1, 1, 1)
types = c("C", "C", "B", "B",
"B")
bounds = NULL
