hm, it's 4.0.2. Not the latest & greatest but i've been using it for 2
years and this would be the first time it miscompiles a 32-bit kernel
out of tens of thousands of successful kernel bootups.

Hm, are you sure? This is a CONFIG_DEBUG_PAGEALLOC=y kernel, so even a
slight overrun of a non-NIL terminated string (as suspected by Al) could
run into a non-mapped kernel page. (which would indicate not a compiler
bug but use-after free)
i just found another config under which i get similar crashes, config
attached. One common theme is CONFIG_DEBUG_FS and DEBUG_PAGEALLOC - and
CONFIG_MAC80211_DEBUGFS is not enabled in this one so it's off the hook
i think. (the crashes are attached below)
(my serial log on this box goes back about 6 months, and that alone
shows more than 3500 successful kernel bootups on that particular
testsystem, each kernel built by this compiler - and there's another
testsystem that i use even more frequently. Despite that, a compiler bug
is still possible of course.)
