Subject: Re: Typo in atexit.c (?)
As I see, this turned out to be a combination of a local patch applied to
atexit.c.
The patch introduces cleanup of additionally allocated fl chunks allocated
by calloc calls in __cxa_atexit.
I think I can upstream the patch upon a brief adaptation to match the
styleguide.
What do you think?
NB: I am not a subscriber of this list and would like to be cc'd with any
replies.
Thanks in advance.
Yuriy.
