Bug ID: 122052
Summary: SPEC CPU2017 654.roms_s fails to run correctly on
AArch64 with GCC 15.1/15.2
Product: gcc
Version: 15.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: edison_chan_gz at hotmail dot com
Target Milestone: ---
Component: libgfortran / runtime
Version: GCC 15.1 / 15.2
Platform: AArch64 (armv9.3-a), OS: Android 16 (Termux Proot Ubuntu 24.04)
Description: When running SPEC CPU2017 benchmark 654.roms_s compiled with GCC
15.1/15.2 on an AArch64 system, the benchmark fails during execution with
return code rc=33792. Compilation completes successfully, but the binary
crashes immediately upon invocation.
The issue is reproducible with the following configuration:
GCC installed at /home/edison/gcc15
Compilation flags include -Ofast -march=armv9.3-a -static
Fortran flags: -fallow-argument-mismatch -fall-intrinsics
SPEC portability flags: -DSPEC_LP64
SPEC version: CPU2017 v1.1.9
ERROR Output:
child finished: 0, pid=31857, rc=33792
error: a total of 1 children finished with errors
Invalid run; unable to continue.
Environment Variables:
LD_LIBRARY_PATH=/home/edison/gcc15/lib64/:/home/edison/gcc15/lib/:/lib64
OMP_NUM_THREADS=1
OMP_THREAD_LIMIT=1
Steps to Reproduce:
Build SPEC CPU2017 with GCC 15.1/15.2 using the provided config file (attached
below).
Run benchmark 654.roms_s with reference input ocean_benchmark3.in.
Observe immediate failure with non-zero exit code.
Expected Behavior: Benchmark should complete successfully and produce valid
output.
Actual Behavior: Benchmark crashes immediately with rc=33792.
Additional Info:
The issue does not occur on x86_64 with the same GCC version and flags.
Other Fortran benchmarks (e.g., 627.cam4_s, 628.pop2_s) run successfully.
