Hi, linux distros are trying to harden with the noexecstack and the execstack in decoder.f90 is causing problems. E.g. [1], [2]. It seems the g++ linker doesn't allow combination of binaries with exec/noexec stacks [1], so the whole binary needs to be compiled with the execstack which may be unacceptable for some distros. The patch proposed in [1] uses mprotect, should something similar be upstreamed?
