|

#
|

# * iconv/gconv_cache.c (find_module): Demangle init_fct before

|
||||
# * iconv/gconv_db.c (free_derivation): Check that __shlib_handle
|
||||
# is non-NULL before demangling the end_fct. Check for NULL
|
||||
# end_fct after demangling.
|
||||
# (__gconv_release_step): Demangle the end_fct before checking
|
||||
# it for NULL. Remove assert on __shlibc_handle != NULL.
|
||||
# (gen_steps): Don't check btowc_fct for NULL before mangling.
|
||||
# Demangle init_fct before checking for NULL.
|
||||
# (increment_counter): Likewise
|
||||
# * gconv_dl.c (__gconv_find_shlib): Don't check init_fct or
|
||||
# end_fct for NULL before mangling.
|
||||
# * wcsmbs/btowc.c (__btowc): Demangle btowc_fct before checking
|
