Please include the complete backtrace with any bug report. See <https://gcc.gnu.org/bugs/> for instructions. NOTE, this error is repeated with -fprofile-use, and the pre-generated profiling data file predict.gcda is generated with gcc11 as following: Target: aarch64-unknown-linux-gnu Configured with: ../latest_gcc_2/configure --prefix=/home/qinzhao/Install/latest-2 --enable-languages=c,c++,fortran,lto --disable-bootstrap Thread model: posix Supported LTO compression algorithms: zlib gcc version 11.0.1 20210304 (experimental) (GCC) since the error depends on the profiling feedback data, the testing case cannot be reduced by hand or by tool (Creduce), I have to attach the complete preprocessed file to repeat the error.
