We can potentially detect at configure time that libc has a particular bug, and that's a useful strategy for things that we can work around by substituting our own implementation. But locale stuff isn't at all feasible to reimplement: our only strategy for it is to call libc, and the most we could do based on a configure test is to decline to call libc on arguments that we think it'll mishandle. We should only thus limit the functionality when we're sure that libc would in fact crash. Crucially, the configure test can't tell us when libc's bug gets fixed post-installation, nor can we test for the bug at runtime when the result of the test may be a crash. So any such crash avoidance would inevitably cause us to refuse to process locales in some situations where it would actually have worked. -zeframThread Previous | Thread Next
