A couple of days ago I fixed an error in svn trunk for ARMEL that  
caused the stack to become temporarily unbalanced after performing  
syscalls with 5 or more parameters (the bug is still there for OABI,  
but I can't fix that because I don't have access to an OABI machine).

A side-effect of that bug was that if the caller passed the address of  
its own result as one of the parameters to the system call, it would  
afterwards return a random value as its result and checks for error  
results caused random failures like the one you posted (the  
reproducible case that allowed me to fix it was a similar error).
