Linux - Output File XXX Absent

Interesting problem.

The "Required frequency-bins [-7, 8]" (i.e. requesting a negative frequency bin) is an error we had frequently in early S5R2/3 App versions. It happens when a certain variable becomes a NaN, which can't be explained from the code (or the data files), but just from a problem on the machine (in very rare cases the App file might got corrupted after being downloaded and checked for integrity).

Recent Apps that use the x87 FPU for these calculations are meant to throw a FPE (signal 8) at this point. Certain Linux Kernel versions caused this problem due to their FPU register handling, it has been fixed in latest versions, though.

The SSE2 App (*_2), however, doesn't use the x87 FPU for the calculations in question. For the moment I can't say whether this is a similar bug e.g. in the Linux Kernel or a hardware problem on that machine - I'm inclined to suspect the latter, but am not fully sure.

Mods, please keep an eye on such reports from the rather new SSE2 App.
