Bug 940571 – sys-devel/gcc-14: ICE when building app-cdr/redumper::tatsh-overlay

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Andrew Udvare 2024-10-01 01:24:19 UTC]

The package builds fine with Clang.

Ebuild: https://github.com/gentoo-mirror/tatsh-overlay/blob/master/app-cdr/redumper/redumper-411.ebuild

Requires setting USE=-clang by force to test this.

MAKEOPTS=-j1 CFLAGS="-O2 -flto=auto -ggdb -march=native -mtune=native -pipe" will cause an ICE:

With jobs set to higher than 1, a different error occurs along with the ICE but I will worry about that one later.

With -save-temps alone, an ICE occurs on the first file.

Work directory, compiled with -save-temps

[Comment 5 Sam James 2024-10-01 02:16:45 UTC]

Can you upload a standalone testcase please?

Run the command which fails manually in the builddir with -save-temps, then copy the .ii it makes to /tmp/foo or whatever, then run the command again in there but with the path to .cc replaced by .ii so it's standalone.

[Comment 6 Andrew Udvare 2024-10-01 22:17:01 UTC]

Testcase

.ii file and required modmap file.

Extract and run `make`. The failing command:
