Bug ID: 118574
Summary: [15 regression] Crashes with coroutines in KDE Plasma
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: c++-coroutines, needs-bisection, needs-source,
wrong-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
CC: arsen at gcc dot gnu.org, iains at gcc dot gnu.org
Target Milestone: ---
I'm filing this as a placeholder for now as we're now in stage 4 and it's
important this one not be forgotten.
When using KDE Plasma compiled w/ trunk, I see a bunch of coro-related crashes:
* one machine consistently has plasmashell crash if I disconnect from a wifi
network in plasma-nm
* another machine crashes easily on plasmashell startup in powerdevil when
checking display info for brightness
Building with GCC 14 or Clang works fine.
This is with Iain's patches for PR116506 and PR116914 applied as well. I've
already discussed it with Iain a bit and the hope is that this is actually a
dupe of one of the other open coro issues.
I don't yet have a testcase for it. I'll post backtraces when I next get a
chance (but obviously both current reproducers are disruptive if there's any
ongoing work).
