Fails with -O1 as well, although I have to admit that different -O levels are deeply integrated in qemus build system. So it is hard to overwrite "all of them". Therefore - while I set -O1 and that affected some builds, it isn't implying that all compiler calls were -O1. I know dannf has made some bare-metal tests and so far none of those have failed. Unfortunately our builders are VM based, so that isn't very helpful anyway. Never the less I've transported my test container over to a box to build there.

[Bug 1890435] Re: gcc-10 breaks on armhf (flaky): internal compiler error: Segmentation fault
FYI - another 8 runs without a crash on r10-7093. My current working theory is that the root cause of the crash might have been added as early as r10-4054 but one or many later changes have increased the chance (think increase the race window or such) for the issue to trigger. If that assumption is true and with the current testcase it is nearly impossible to properly bisect the "original root cause". And at the same time still hard to find the one that increased the race window - since crashing early does not surely imply we are in the high/low chance area. We've had many runs with the base versions so that one is really good. But any other good result we've had so far could - in theory - be challenged and needs ~30 good runs to be somewhat sure (puh that will be a lot of time). I'm marking the old runs that are debatable with good?. Also we might want to look for just the "new" crash signature. 20190425 good r10-1014 r10-2027 good?4 r10-2533 r10-3040 good?4 r10-3220 r10-3400 good?4 r10-3450 r10-3475 r10-3478 r10-3593 r10-3622 r10-3657 good?5 r10-3727 good?3 r10-4054 other kind of bad - signature different, and rare? r10-6080 good?10 r10-7093 bad, but slow to trigger 20200507 bad bad bad Signatures: r10-4054 arm_legitimate_address_p (nonimmediate) r10-7093 add_regs_to_insn_regno_info (lra) r10-7093 add_regs_to_insn_regno_info (lra) 20200507 extract_plus_operands (lra) 20200507 avoid_constant_pool_reference (lra) 20200507 add_regs_to_insn_regno_info (lra) ubu-10.2 add_regs_to_insn_regno_info (lra) ubu-10.2 avoid_constant_pool_reference (lra) ubu-10.2 thumb2_legitimate_address_p (lra) ubu-10.2 add_regs_to_insn_regno_info (lra) Of course it could be that the same root cause surfaces as two different signatures - but to it could as well be a multitude of issues.

r10-6080 now had 10 good runs.

We had a datacenter move, so the cloud runs on the same bare metal overall, but my instance could run on something else today than last week.

For the sake of a potential upstream change I was trying qemu from git up to current master, but it still fails with the same error: ‘TYPE_CANONICAL’ is not compatible.

I've learned that the gcc in hirsute has the checking enabled atm. That explains why any qemu 5.1 build I do (merging) or Doko's rebuild on [1] fail atm.

I've been able to reproduce reliably on X-Gene gear when running in a KVM instance. I have not been able to reproduce outside of KVM, nor on an alternate SoC (Hi1616). I *can* reproduce on a xenial kvm guest running on a xenial X-Gene host - which suggests that correlation with the LP builder upgrade is likely just coincidence. I also tried an older xenial guest kernel just in case there was a kernel patch that was backported to all releases that may have broke things - but I was also able to reproduce there. If I were to draw a conclusion at this stage, it would be that there may very well be a low level issue causing this but, if so, it is unlikely a new one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890435 Title: gcc-10 breaks on armhf (flaky): internal compiler error: Segmentation fault To manage notifications about this bug go to: https://bugs.launchpad.net/groovy/+bug/1890435/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Interim Summary: - hits armhf compiles of various large source projects, chances are it it completely random and just hits those more likely by compiling more - build system auto-retries the compiles and they work on retry eventually reported as "The bug is not reproducible, so it is likely a hardware or OS problem." - The bug always occurs on different source files, retrying a failed one works for hundreds of times so it seems to be sort of random when it hits and not tied to the source. - It seems we need concurrency to trigger it, but again it might just have increases the likeliness - I can trigger it reliably now in ~2-8h of compile time on Canonistack when building qemu on an armhf LXD container on a arm64 Hosts (same as the builders) - Despite my tries I'm unable to gather a crash dump of the gcc segfault and would be happy about a hint/advise on that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890435 Title: gcc-10 breaks on armhf (flaky): internal compiler error: Segmentation fault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-10/+bug/1890435/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
