Subject: bug#53347: Compilation error on package Papi 5.5.1

Hi,

The package [email-masked] does not compile. It fails with an error during the build phase :

‘%s’ directive output may be truncated writing up to 255 bytes into a region of size between 0 and 4095 [-Werror=format-truncation=]

While this is a problem in the application itself, GCC started diagnosing these problems in version 7.1¹ and expanded coverage in version 8², so a change in the compiler version probably triggered the problem.

Also, I believe this is fixed in newer releases of PAPI³ but I don't know if updating the version would be acceptable.
