When running 2.4.0 on an ARM system (Debian v5 "Lenny", armel) with limited memory (32Mb RAM + 768Mb swap) and using it to compile a large project (Lazarus 0.9.28.2) I'm seeing intermittent failures which go away if the make is restarted. I've not seen this running on other platforms, and I don't believe it is a problem in the Lazarus sources since the build will eventually complete giving me runnable code.
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).
