glibc error: corrupted double-linked list

[Fabio Comolli]

Hi all.
With latest rawhide (glibc-2.4.90-26 and firefox-1.5.0.6-9) I
experimented some random firefox hangs.
Running firefox from command line I got the attached trace.
Kernel is 2.6.18-rc4-mm1.
Please let me know if you need more details.
