863	tester malloc3 causes kernel panic on QEMU 7.2/8.0 (amd64)	Jiří Zárevúcky		"This happens at least with QEMU 7.2 and QEMU 8.0,
as of commit d4643dba... and also going several years back, so it's not a recent regression, but seems to be some kind of interaction with newer QEMU versions, as QEMU 6.2.0 built from source does not trigger this.

Should be worth investigating.
