при обновлении системы valgrind теперь матерится на любое приложение, что очень неудобно при отладке, как это исправить?

Проинициализировать переменные?

Последние пять сообщений - как уже сказали - инициализовать переменную. Первые девять - валгринду скормить заглушку, дабы он их не показывал.

насчет последний сообщений ясно, просто кусок выдрал, ну а сообщение первого типа никогда раньше не появлялись, я просто думал что проблема где то в библиотеках...

А можно поподробнее о том, что есть заглушка и как ею кормить валгринд?

Есть так называемые suppresions, в fedore они болтаются в ls -la /usr/lib64/valgrind/*supp, там указываются ошибки, которые не должны быть показаны пользователю. Например, /usr/lib64/valgrind/glibc-2.5.supp:

##----------------------------------------------------------------------##

# Errors to suppress by default with glibc 2.5.x

# Format of this file is:
# {
# name_of_suppression
# tool_name:supp_kind
# (optional extra info for some suppression types)
# caller0 name, or /name/of/so/file.so
# caller1 name, or ditto
# (optionally: caller2 name)
# (optionally: caller3 name)
# }
#
# For Memcheck, the supp_kinds are:
#
# Param Value1 Value2 Value4 Value8 Value16
# Free Addr1 Addr2 Addr4 Addr8 Addr16
# Cond (previously known as Value0)
#
# and the optional extra info is:
# if Param: name of system call param
# if Free: name of free-ing fn)

{
dl-hack1
Memcheck:Cond
fun:_dl_start
fun:_start
}

{
dl-hack2
Memcheck:Cond
obj:/lib*/ld-2.5*.so
obj:/lib*/ld-2.5*.so
obj:/lib*/ld-2.5*.so
obj:/lib*/ld-2.5*.so
}

{
dl-hack3
Memcheck:Cond
obj:/lib*/ld-2.5*.so
obj:/lib*/ld-2.5*.so
obj:/lib*/ld-2.5*.so
}

и т.д.
