Hi, 23f128ad5e2b causes problems when the environment isn't wholly sanitized. Specifically, pattern matching such as: if [[ "$(declare -p $i)" != "declare -a "* ]]; then Is too brittle. You can easily "break" makepkg by doing something like: export arch=; makepkg And makepkg will error out with: ==> ERROR: arch should be an array It *is* an array, but the decl looks like: declare -ax arch='([0]="i686" [1]="x86_64")' And the originally stated pattern matching fails. If we want to continue to match arrays based on this sort of introspection, we should make the pattern a bit more robust -- something like: if [[ $(declare -p "$i") != declare\ -*([[:alnum:]])a*([[:alnum:]])\ * ]]; then And this would be immune to other attributes which might show up in the output of 'declare -p'. Cheers, dR
