[Rd] Bug in nlm()

Dear all, I have found a bug in nlm() and would like to submit a report on this. Since nlm() is in the stats-package, which is maintained by the R Core team, bug reports should be submitted to R's Bugzilla. However, I'm not a member of Bugzilla. Could anyone be so kind to add me to R's Bugzilla

Re: [Rd] Bug in nlm, found using sem; failure in several flavors (PR#13883)

A wild guess, based on some recent non-deterministic behavior in lme4: could this be driven by a bug in optimized linear algebra libraries (BLAS/LAPACK)? (Unfortunately, I'm not clear on how to check the versions of BLAS/LAPACK being used and whether they are subject to bugs, but perhaps

Hi Jeff, As mentioned in my message, I *did* replicate on another platform. One platform was running linux in a VM, the other running MacOSX, on two different physical machines. The problem did not replicate on a PowerPC box, so if it is a bug with intel chips, I think it's also appropriate

Adam, It seems that your attachment didn't make it through. That aside, my experience with strange errors like those (random type not implemented ones) has been that you may be looking at a memory problem on you machine. Given that you can't replicate on another platform (and the .csv file
