Bug ID: 121791
Summary: compiling simplify-rtx.cc fails in stageprofile of
profiledbootstrap build
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: defsyn at gmail dot com
Target Milestone: ---
Created attachment 62302
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=62302&action=edit
tar.xz file of the two mentioned files.
Architecture: AMD64 on Debian Trixie
Compiler: using gcc-15.2.0 to build gcc suite 16.0.0
Machine config:
Intel Xeon E5-2695 -v4, 128GB RAM
Reproducible:
Yes. Consistently fails in the stageprofile stage. However, will not fail, if
using a standard default 3 stage build.
Included for inspection in attachment:
1. Complete build log from 2>&1 | tee -a buildgcc.log ( make -j72
profiledbootstrap 2>&1 | tee -a buildgcc.log )
2. simplify-rtx.i from the command that fails in the build process.
Appears to be an uninitialized variable.
