--- Comment #7 from Bernd Edlinger <bernd.edlinger at hotmail dot de> --- without looking in detail, this could be another middle-end error or the back-end generating an invalid instruction where no assertions are, then lra can rewrite the insn in a way that triggers the assertion later. I have no resources to work on reducing this due to the upcoming OpenSSL release tomorrow, were I need to work on a fix for a CVE I found. Could you pleas help reducing this one?
