Bug#249559: vsyslog fails

[fumihiko kakuma <kakmy@mvh.biglobe.ne.jp>]

Package: libc6
Version: 2.2.5-11.5

vsyslog() fails if a return from open_memstream() is error.
The reason is that when the return from open_memstream() is error,
a variable buf is set a stack pointer of a variable failbuf
and the buf with the stack pointer is freed last.

I think that you would have to check the buf before freeing
it whether the buf have the stack pointer.
