I'm experimentally rebuilding rawhide with the not-yet-released GCC 15 to see if anything breaks, and to help write the porting guide. See https://fedoraproject.org/wiki/User:Dmalcolm/gcc-15 My test build with GCC 15 failed: https://copr.fedorainfracloud.org/coprs/dmalcolm/gcc-15-smoketest-3.failed/build/8476284/ whereas my test build with GCC 14 succeeded: https://copr.fedorainfracloud.org/coprs/dmalcolm/gcc-15-smoketest-3.failed.checker/builds/ Looking at the failure logs e.g. https://download.copr.fedorainfracloud.org/results/dmalcolm/gcc-15-smoketest-3.failed/fedora-rawhide-x86_64/08476284-dyninst/builder-live.log.gz I see: /builddir/build/BUILD/dyninst-12.3.0-build/dyninst-12.3.0/dyninst-12.3.0/instructionAPI/src/AMDGPU/gfx908/InstructionDecoder-amdgpu-gfx908.C: In member function ‘Dyninst::InstructionAPI::Expression::Ptr Dyninst::InstructionAPI::InstructionDecoder_amdgpu_gfx908::makePCExpr()’: /builddir/build/BUILD/dyninst-12.3.0-build/dyninst-12.3.0/dyninst-12.3.0/instructionAPI/src/AMDGPU/gfx908/InstructionDecoder-amdgpu-gfx908.C:89:54: error: call of overloaded ‘makeRegisterExpression(Dyninst::MachRegister&)’ is ambiguous 89 | return makeRegisterExpression(baseReg); | ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~ In file included from /builddir/build/BUILD/dyninst-12.3.0-build/dyninst-12.3.0/dyninst-12.3.0/instructionAPI/src/AMDGPU/gfx908/InstructionDecoder-amdgpu-gfx908.h:31, from /builddir/build/BUILD/dyninst-12.3.0-build/dyninst-12.3.0/dyninst-12.3.0/instructionAPI/src/AMDGPU/gfx908/InstructionDecoder-amdgpu-gfx908.C:32: /builddir/build/BUILD/dyninst-12.3.0-build/dyninst-12.3.0/dyninst-12.3.0/instructionAPI/src/InstructionDecoderImpl.h:73:33: note: candidate: ‘virtual Dyninst::InstructionAPI::Expression::Ptr Dyninst::InstructionAPI::InstructionDecoderImpl::makeRegisterExpression(Dyninst::MachRegister, uint32_t)’ 73 | virtual Expression::Ptr makeRegisterExpression(MachRegister reg, uint32_t num_elements = 1); | ^~~~~~~~~~~~~~~~~~~~~~ /builddir/build/BUILD/dyninst-12.3.0-build/dyninst-12.3.0/dyninst-12.3.0/instructionAPI/src/AMDGPU/gfx908/InstructionDecoder-amdgpu-gfx908.h:302:29: note: candidate: ‘Dyninst::InstructionAPI::Expression::Ptr Dyninst::InstructionAPI::InstructionDecoder_amdgpu_gfx908::makeRegisterExpression(Dyninst::MachRegister)’ 302 | Expression::Ptr makeRegisterExpression(MachRegister registerID); | ^~~~~~~~~~~~~~~~~~~~~~ Not yet sure what's going on here.

Reproduced. Started with commit 06557ba12b64c57368673c46a21b14cf4e6afb50 Author: Patrick Palka <ppalka> Date: Fri Sep 20 12:31:40 2024 -0400 c++: CWG 2273 and non-constructors Our implementation of the CWG 2273 inheritedness tiebreaker seems to be incorrectly considering all member functions introduced via using, not just constructors. This patch restricts the tiebreaker accordingly. so I think the error is expected.
Yeah, GCC is behaving correctly here AFAICT. The bug seems to be fixed upstream in dyninst v13 by https://github.com/dyninst/dyninst/commit/42c3a4b497071e421686ded49ad0da406c8053ac
The failed to build has been addressed with dyninst-13.0.0-4.fc42.
