--- Comment #10 from Ian Lance Taylor <ian at airs dot com> --- I can't recreate the problem. I did the same commands in github.com/twstrike/ed448 and they worked for me. Using `go test -c -gccgoflags -Wl,--compress-debug-sections=zlib` to generate an executable, and using `readelf -S --wide` to look at the section headers, I can see that the debug sections are compressed: [31] .debug_info PROGBITS 0000000000000000 1e15d8 012fb5 00 C 0 0 1 [32] .debug_abbrev PROGBITS 0000000000000000 1f458d 00062d 00 C 0 0 1 [33] .debug_aranges PROGBITS 0000000000000000 1f4bc0 0000d9 00 C 0 0 16 [34] .debug_line PROGBITS 0000000000000000 1f4c99 00782b 00 C 0 0 1 [35] .debug_str PROGBITS 0000000000000000 1fc4c4 00626e 01 MSC 0 0 1 [36] .debug_ranges PROGBITS 0000000000000000 202732 000201 00 C 0 0 1 [37] .debug_loc PROGBITS 0000000000000000 202933 000b62 00 C 0 0 1
