zttool fails with realloc(): invalid next size [SOLVED]

[quad]

Hi,
I've upgraded an old 2.6.12 kernel to 2.6.22-r5 yesterday on a PBX box running asterisk. Now when I try to configure the zaptel driver with zttool, the following messages appear on a blue background:

Code: Select all

*** glibc detected *** zttool: realloc(): invalid next size: 0x0805b7b0 ***
======= Backtrace: =========
/lib/libc.so.6[0xb7eb9710]

/usr/lib/libnewt.so.0.51(newtFormAddHotKey+0x36)[0xb7f83de6]
...

It is followed by a Memory Map dump.
I'm not sure where the problem is. I've tried to reinstall asterisk && zaptel by first cleaning the modules in /lib/modules/*/misc, but no luck for me.

Did anyone ever came across a similar error? What could it mean?

Found the fix. A bug seems to exist in dev-libs/newt-0.51.6-r1 which was causing the error. Upgrading to the unstable 0.52.2 fixed it.
