Follow-up Comment #4, bug #61073 (project groff):
The difference lies in the use of different software (gnulib).
Check what "-fanalyze" does with youn own flags.
I get seven warnings about
dereference of NULL '<unknown>' [CWE-690] [-Wanalyzer-null-dereference]
and one about
warning: leak of FILE 'fp' [CWE-775] [-Wanalyzer-file-leak]
and a compiler error
during IPA pass: analyzer
../src/utils/addftinfo/addftinfo.cpp: In function 'int main(int, char**)':
../src/utils/addftinfo/addftinfo.cpp:121:5: internal compiler error: in
get_or_create_mem_ref, at analyzer/region-model.cc:6938
121 | if (sscanf(argv[i+1], "%d", &(param.*(param_table[j].par))) != 1)
| ^~
0x7f16283b5d09 __libc_start_main
../csu/libc-start.c:308
Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <file:///usr/share/doc/gcc-10/README.Bugs> for instructions.
I am waiting for an updated version of the compiler (from 10.2.1-6 Debian).
(And an update of libc6 (glibc) from 2.31-13)
