Bug ID: 107552
Summary: [13 regression] stage 1 d21 fails to link on
Linux/x86_64
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-pc-linux-gnu
Target: x86_64-pc-linux-gnu
Build: x86_64-pc-linux-gnu
I've long been bootstrapping trunk with GCC 9.3.0. However, between 20221028
(11e811d8e2f63667f60f73731bb934273f5882b8) and 20221104
(e724b0480bfa5ec04f39be8c7290330b495c59de),
bootstrap broke linking stage 1 d21:
/vol/gcc/bin/gld-2.35: d/typesem.o:(.data+0x180): multiple definition of
`___s.24340'; d/statementsem.o:(.data+0x260): first defined here
collect2: error: ld returned 1 exit status
make: *** [/vol/gcc/src/hg/master/local/gcc/d/Make-lang.in:234: d21] Error 1
I've tried with GCC 11.1.0: while the stage 1 d21 links this way, the resulting
gdc/d21 fails to run because d21 is linked with libstdc++ dynamically, using a
version that's newer than the one bundled with Ubuntu 20.04. Passing through
LD_LIBRARY_PATH is tricky and does cause a couple of testsuite regressions.
GCC 12.1.0 does work, and stage 1 d21 is linked statically with libstd++, as
expected. However, this means quite massive an increase in build requirements.
