kernel panic when running cmake (not every time)

[myob]

I'm getting a kernel panic when running cmake on CorsixTH (​http://code.google.com/p/corsix-th/), not every single time however. Only when a file relating to cmake has been modified, e.g. the linker list or similar.

Panic is "vnode already exists (node = 0x00c24050, vnode->node = 0x00000000

Does checkfs detect any errors?

[myob]

checkfs -c /boot

268734 nodes checked, 
0 blocks not already allocated, 
0 blocks already set, 
26779 blocks could be freed

doesn't look that odd?

[axeld]

No, not at all; blocks that can be freed usually means that a file had been deleted, but its space could not be freed during the runtime because of a kernel crash or an unexpected power loss (it's a BFS shortcoming).

Not reproductible anymore, cmake runs fine and can build Corsix-TH without problems now. Does it still happen for you?
