[Pw_forum] invalid flag

[Hugo Siles]

Hello,

I have installed espresso-5.2.1 on fedora 22, with some minor difficulties, but it has been installed, I run all the tests, and as far as I could see all of them passed.
However when running one of the samples from the tutorials with the following command:
pw.x <Si.sample.in> Si.sample.out 
I get the following message during execution:









[hsiles at localhost exercise1]$ pw.x <Si.sample.in> Si.sample.out

Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG IEEE_DENORMAL.

There is an output file
 
Does the message means any thing to worry about ??
