Paolo Carlini ab940869ea re PR libstdc++/24450 (Exception safety problem in messages/__timepunct)
2005-10-21  Paolo Carlini  <pcarlini@suse.de>

	PR libstdc++/24450
	* config/locale/generic/time_members.h (__timepunct<>::
	__timepunct(__c_locale, const char*, size_t)): Avoid leaking
	memory if new throws inside _M_initialize_timepunct.
	* config/locale/gnu/time_members.h (__timepunct<>::
	__timepunct(__c_locale, const char*, size_t)): Likewise.
	* config/locale/gnu/message_members.h (messages<>::
	messages(__c_locale, const char*, size_t)): Rearrange to
	avoid memory leaks.
