Hi everybody,
The latest java-1.8.0-openjdk update for rawhide (the first build with GCC 10) seems to have introduced some serious problems - including crashes and segmentation faults during package builds for Java packages.
The broken update landed in rawhide with the Fedora-Rawhide-20200313.n.0 compose: java-1.8.0-openjdk-1:1.8.0.242.b06-0.0.ea.fc32 -> java-1.8.0-openjdk-1:1.8.0.242.b08-0.fc33
I haven't been able to reproduce the crashes reliably, so I assume it's something that's either randomly triggered, or dependent on the specific hardware / architecture (but this seems to affect at least x86_64, i686, and aarch64, so I'm not so sure it's architecture related).
koschei started complaining about a whole lot of Java packages since the update landed:
https://koschei.fedoraproject.org/affected-by/java-1.8.0-openjdk-headless?ep...
The same java-1.8.0-openjdk update has also landed in f32 updates-testing, but I haven't been able to reproduce any crashes with that version (so far), so I'm not sure if this is also affecting the f32 update, or if it's isolated to rawhide.
Here's the - seemingly unaffected - f32 update for the same version: https://bodhi.fedoraproject.org/updates/FEDORA-2020-af190951f6
I've reported this issue here: https://bugzilla.redhat.com/show_bug.cgi?id=1813550
Does somebody have experience with debugging the JVM? Please help :D

The OpenJDK package itself is no different to the one that's been in earlier versions of Fedora since January [0] [1]. I believe GCC 10 is the issue here.
It has taken a significant effort to even get java-1.8.0-openjdk to build with GCC 10 [2], mainly by turning off a number of optimisations, and a backlog of changes has built up. We really need to be getting these packages updated for the next security update this time next month.
Do you know if F32 & rawhide are using the same GCC?

I belive so.
It has taken a significant effort to even get java-1.8.0-openjdk to build with GCC 10 [2], mainly by turning off a number of optimisations, and a backlog of changes has built up. We really need to be getting these packages updated for the next security update this time next month.

fedora 32 and rawhide have the same version of GCC (10.0.1). rawhide is at: gcc-10.0.1-0.9.fc33 fedora 32 has gcc-10.0.1-0.8.fc32 in stable, and gcc-10.0.1-0.9.fc32 in updates-testing.
I've now been able to reproduce JVM crashes with the java-1.8.0-openjdk build from fedora f32 updates-testing as well (which is the first build of openjdk with GCC 10).

Yet another gcc10-related headache... I'm experiencing issues building rstudio in rawhide for i686: https://koji.fedoraproject.org/koji/taskinfo?taskID=42614405. But I believe this is not the best package to chase the bug. No issues so far in F32, but you said this fails randomly?
