I'm also seeing unusual behavior from GSL under ghc-6.8.1. I get a singular matrix error where there was none before, but if I prefix the function's rhs with "m `seq`", where m is the matrix in question, the error goes away. I'll try removing the seq and compiling with -fvia-C tomorrow to see if I can confirm that that makes the problem go away too. Certain inputs cause it to fail repeatably, while others do not fail; I'm not seeing random behavior like Alberto is. Strange indeed. -- Joel
