Hi folks!
There seems to be some evidence that the latest gnutls might be involved
in instabilities of the adobe flash plugin for mozilla firefox on gentoo
linux.
I myself got this error message and back trace at one point:
*** glibc detected *** /usr/lib/mozilla-firefox/firefox: realloc():
invalid next size: 0x1026c8f0 ***
======= Backtrace: =========
/lib/libc.so.6[0x4c59d7c4]

/opt/netscape/plugins/libflashplayer.so[0xb213de16]
http://bugs.gentoo.org/272388#c7 lists a similar back trace, with
"double free or corruption (!prev)" instead of "invalid next size".
http://bugs.gentoo.org/260630 might be dealing with the same bug.
In all these cases, the latest (and rather recently released) closed
source flash player was involved as well, so I cannot rule out a problem
with that code. You might wish to investigate the issue on the gnutls
side nevertheless, and maybe subscribe to those bugs to stay tuned.
