is System.system broken in 5.04? i am using the rpm provided on the web site and this call appears to be broken. in particular, using strace i find that it is attempting the following call

[pid 16975] execve("n/sh", ["/bin/sh", "-c", "echo foo"], [/* 67 vars */]) = -1 ENOENT (No such file or directory)

note that it appears the first three characters are being droped from the first argument to execve.

I haven't seen any problems with System.system here (the compiler uses it quite extensively for one). Which flavour of Linux are you on, and do you have a test program we can use to reproduce it? Cheers, Simon
