Sorry for the delay of this reply, I was on a trip last week. I am running the test on a Mac, specifically on a MacBook Pro, with Mac OS 10.4.10 and gsl 1.9 installed. The test also fails on various linux boxes I tried (e.g., RedHat with kernel 2.6.18, or Debian with kernel 2.6.21). As far as I can tell, the problem is there also in gsl 1.8.
I suspect that you cannot reproduce the bug because the data file was not correctly transfered or read. To (at least) exclude the first possibility, here is the md5 checksum of the file: $ md5sum gsl-test.dat 768b5a964b8ce98932ed0618ac9f97e1 gsl-test.dat Regards, Marco Lombardi On 8/3/07, Brian Gough <[EMAIL PROTECTED]> wrote: > At Thu, 2 Aug 2007 10:31:22 +0200, > Marco Lombardi wrote: > > occasionally I find that gsl_multifit_wlinear_svd never returns.
