Bug ID: 125130
Summary: g++ stack overflow ICE when building clksignal
2026-04-30
Product: gcc
Version: 16.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ats-gccbugs at offog dot org
Target Milestone: ---
Created attachment 64338
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=64338&action=edit
Minimised example producing ICE
The attached code is minimised from Archimedes.cpp from clksignal 2026-04-30
(https://github.com/TomHarte/CLK).
The same code on Compiler Explorer: https://godbolt.org/z/PPPj6vev4
It causes an ICE with 16.1.0 for x86_64-pc-linux-gnu native. It appears to do
the same for other platforms and with trunk according to Compiler Explorer.
(After the ICE, the driver also crashes so there's no "Please submit ..."
message, but I've filed bug 125128 about that separate problem.)
Invocation:
$ g++ -v -c gccbug-202605a.cc

g++: internal compiler error: Segmentation fault signal terminated program

Segmentation fault g++ -v -c gccbug-202605a.cc
Running cc1plus under valgrind says that it's a stack overflow, and the gdb
backtrace shows that it's in infinite recursion - here's the first 200 frames:
