is_dcp has difference results on difference system (Mac, Linux and Windows)

[weizhoujp]

Describe the bug
I ran a quadratic optimization by CVXR on Linux , Mac and Windows:

It's fine when i run code on windows and is_dcp(prob) returns true.

However, when I run the code on Linux and Mac. Some errors occured:

Error in construct_intermediate_chain(object, candidate_solvers, gp = gp) :
Problem does not follow DCP rules. However, the problem does follow DGP rules. Consider calling this function with gp = TRUE
Calls: byCVXR ... construct_intermediate_chain -> construct_intermediate_chain
Execution halted

To Reproduce
please load the R file and Rdata on https://uwmadison.box.com/s/eodz9ll2mrhqgq18do77dir6dekdx8xu.
(byCVXR.R cheak.RData)
and run : result <- byCVXR(summary.stat.study.F.sw,lambda_1 = len_lambda1[1] ,lambda_2 = len_lambda2[1],method='MetaMic')
