Bug ID: 122363
Summary: Testcase gfortran.dg/pdt_22.f03 ICEs with
LTO-bootstrapped compiler (only!)
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: jamborm at gcc dot gnu.org
CC: pault at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-linux-gnu
Target: x86_64-linux-gnu
Repeatedly (last time using commit 938ad303f9d), the Fortran testcase
gfortran.dg/pdt_22.f03 passes when I bootstrap the compiler normally, but fails
with an ICE when the compiler is LTO-bootstrapped:
gfortran.dg/pdt_22.f03 -O0 (internal compiler error: in
gfc_add_block_to_block, at fortran/trans.cc:2305)
gfortran.dg/pdt_22.f03 -O1 (internal compiler error: in
gfc_add_block_to_block, at fortran/trans.cc:2305)
gfortran.dg/pdt_22.f03 -O2 (internal compiler error: in
gfc_add_block_to_block, at fortran/trans.cc:2305)
gfortran.dg/pdt_22.f03 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops
-ftracer -finline-functions (internal compiler error: in
gfc_add_block_to_block, at fortran/trans.cc:2305)
gfortran.dg/pdt_22.f03 -O3 -g (internal compiler error: in
gfc_add_block_to_block, at fortran/trans.cc:2305)
gfortran.dg/pdt_22.f03 -Os (internal compiler error: in
gfc_add_block_to_block, at fortran/trans.cc:2305)
The failure pretty much always looks like this:
/home/mjambor/gcc/mine/src/gcc/testsuite/gfortran.dg/pdt_22.f03:28:3: internal
compiler error: in gfc_add_block_to_block, at fortran/trans.cc:2305
