New Revision: 303013
URL: https://svnweb.freebsd.org/changeset/base/303013
Log:
g_Ctoc() conversion buffers are smaller than needed up to MB_CUR_MAX - 1
since whole conversion needs a room for (len >= MB_CUR_MAX). It is no
difference when MB_CUR_MAX == 1, but for multi-byte locales last few chars
('\0' and before) may need just one byte, and the rest of MB_CUR_MAX - 1
space becomes unavailable in the MAXPATHLEN-sized buffer, which cause
conversion error on near MAXPATHLEN long pathes.
Increase g_Ctoc() conversion buffers to MB_LEN_MAX - 1.
