Spot the bugs: int cygwin_spelling (char const *path) { ... int len; ... if (! path || ! *path || len > PATH_MAX) /* PATH will cause EINVAL or ENAMETOOLONG, treat it as non-existing. */ return -1; len = strlen (path); D'oh. But this same flub of mine was also present in at least 8.23-4; so it was the upstream churn in src/cp.c that caused the stack to be different to the point that it now matters. [For those keeping score, I should use size_t and not int to store strlen() values, since it matters on 64-bit when encountering the unlikely >2G string; and it helps to never branch on uninitialized memory] -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
