The dwp file in this directory doesn't parse successfully:

It returns a GimliError(InvalidIndexSlotCount) from this code:

I generated the dwp file with dwp version 2.34 on Ubuntu 20.04.4 LTS in an aarch64 VM, with gcc version 9.4.0.
Here's the script I used to generate it:
#!/bin/bash mkdir -p out/with-dwp # Compile source files into object files g++ -c -g -Os -Wall -Wextra -gsplit-dwarf src/main.cpp -o out/with-dwp/main.o g++ -c -g -Os -Wall -Wextra -gsplit-dwarf src/file1.cpp -o out/with-dwp/file1.o g++ -c -g -Os -Wall -Wextra -gsplit-dwarf src/file2.cpp -o out/with-dwp/file2.o g++ -c -g -Os -Wall -Wextra -gsplit-dwarf src/file3.cpp -o out/with-dwp/file3.o # Create libfile23.a from file2.o and file3.o ar rcs out/with-dwp/libfile23.a out/with-dwp/file2.o out/with-dwp/file3.o # Link libraries into executable g++ out/with-dwp/main.o out/with-dwp/file1.o out/with-dwp/libfile23.a -o out/with-dwp/main # Make dwp file dwp -e out/with-dwp/main # Remove .dwo, .o, .a files rm out/with-dwp/*.dwo out/with-dwp/*.o out/with-dwp/*.a
