Public bug reported:
Using WPA encrypted Wi-Fi on a notebook with "iwlagn" card (Fujitsu
S761) causes random memory corruption.
Tested it with natty's linux-image-2.6.38-10 (both pae and non-pae) and
libc, tried to upgrade kernel and glibc, got the same problem. Seems to
be reproduceable on any kernel.
What it looks like: programs like Firefox, Thunderbird, X server crash
randomly, gcc fails while compiling with weird error messages ("syntax
error" at line 87265876 of file containing only 10 lines), etc.
How to reproduce:
1. Connect to a WPA protected network. (I just use network-manager).
2. Run any CPU- and memory-intensive task, i.e. "povray +W800 +H480 +A0.3
balcony.pov"
There are 99% chances that it will segfault. It NEVER segfaults if the wlan
commection is not WPA-protected.
