--- Comment #8 from Sergei Trofimovich <slyfox at inbox dot ru> ---
Here is the full reproducer: 1200 interdependent files required for a thin
archive.
gcc-11.1.0 + binutils-2.36.1:
$ ./mk.bash
thin archive for 1200
176
gcc-11.1.0 + binutils-2.37:
$ ./mk.bash
thin archive for 1200
/usr/lib/gcc/x86_64-pc-linux-gnu/11.1.0/../../../../x86_64-pc-linux-gnu/bin/ld:
//libthin.a: error adding symbols: malformed archive
Full script:
$ cat mk.bash
#!/bin/bash
rm -rf -- libthin.a main.o m s
mkdir -p s
cc=x86_64-pc-linux-gnu-gcc
ar=x86_64-pc-linux-gnu-ar
nfiles=${1-1200}
for i in `seq 1 ${nfiles}`; do
prev_i=$((i - 1))
printf "extern int a${prev_i}(void); int a${i}(void) { return 1 +
a${prev_i}(); }" > s/a${i}.c
$cc -c s/a${i}.c -o s/a${i}.o
done
printf "int a0(void) { return 0; }; extern int a${nfiles}(void); int main() {
return a${nfiles}(); }" > main.c
$cc -c main.c -o main.o
# thin archive
echo "thin archive for $nfiles" >&2
$ar crsT libthin.a s/a*.o
$cc -pthread -o m -rdynamic -m64 main.o ${PWD}/libthin.a
./m; echo $?
