Hi,
Seems like gentoo-sources (6.6.30, 6.6.37, 6.6.38 and 6.9.8 atleast) fails to build with sys-devel/gcc15 (tried with 15.0.0_pre20240630 and 15.0.0_pre20240707), when | Code: | | CONFIG_HAVE_GCC_PLUGINS=y |
is set - works fine with gcc14.

Seems to say not to bug report it (is that upstream kernel that doesn't want bug report? should it be bug reported anywhere?)

Hello,
The problem is that Linux's randstruct GCC plugin causes the compiler to hit an assert that was recently introduced.
If you disable CONFIG_RANDSTRUCT, the problem goes away.
The warning about not reporting the problem with GCC plugins enabled comes from GCC, not the Linux build.
I reported this issue to the Linux project at https://github.com/KSPP/linux/issues/367 |

Thank you Thiago!
(Also, sorry OP, I thought I'd replied to this -- indeed, it should be reported, as Thiago has done, to the kernel folks, just not to the GCC people unless some investigation is done by the plugin authors first.) |
