Sorry but I was a bit hasty about the reason for crashes on Friday (upgrading Linux is always an experience, especially with the bugginess of all Redhat versions ...) In fact, my library functions calling Fortran all happen to use the %o% operator as well whereas the C ones that I tried do not. The problem is multiplication of 1x1 matrices not Fortran. Try 1%o%1 or y <- matrix(1) y*y Both crash R61.2 on Redhat 5 but not R61.1. However they do not crash my son Patrick's R61.2 on an Amiga with Linux. (His HP portable has been sent back 4 times under guarantee in the last two months. HP guarantees are not worth the ink they are printed with!) 2. A second problem with Redhat 5: ctrl-C does not work (same as with Redhat 4.1). This time, it apparently is not the readline library. I compiled without it and the problem persists: one ctrl-C and then it no longer works. Has anyone any idea what library has the bug? Thanks.
