FWIW, I can reproduce the problem with Config.pm outside of Devel::CheckLib.pm:


C:\test>perl -MConfig -E"say for @Config{ qw[ccflags ldflags] }"
&Config::AUTOLOAD failed on Config::launcher at C:/Perl64/lib/Config.p
+m line 76.

But I've still no real idea why that happens.

My best guess is that %Config is some kind of tied or magic-applied hash and it doesn't like having its elements aliased.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
