As said I hit the problem with Debian's perl v5.34. Checking perl5 Git reveals: "skip using gcc brace groups for STMT_START/END" https://github.com/Perl/perl5/commit/7169efc77525df70484a824bff4ceebd1fafc7= 60 "Partially Revert "skip using gcc brace groups for STMT_START/END"" https://github.com/Perl/perl5/commit/e08ee3cb66f362c4901846a46014cfdfcd6032= 6c Perl v5.34.x seems not to have these changes: https://github.com/Perl/perl5/compare/v5.34.0...v5.34.1 Unsure if there exists a real fix for perl5. - Sedat - > Cheers, > Nathan > > > ----------------------------------------------------- 8< --------------= ----- > > > > =E2=AC=A2[acme@toolbox perf]$ cat /tmp/build/perf/feature/test-libperl.= make.output > > In file included from test-libperl.c:3: > > In file included from /usr/lib64/perl5/CORE/perl.h:4085: > > In file included from /usr/lib64/perl5/CORE/hv.h:659: > > In file included from /usr/lib64/perl5/CORE/hv_func.h:34: > > In file included from /usr/lib64/perl5/CORE/sbox32_hash.h:4: > > /usr/lib64/perl5/CORE/zaphod32_hash.h:150:5: error: '(' and '{' tokens = introducing statement expression appear in different macro expansion contex= ts [-Werror,-Wcompound-token-split-by-macro] > > ZAPHOD32_SCRAMBLE32(state[0],0x9fade23b);
