Component: c
Assignee: unassigned at gcc dot gnu.org

/usr/bin/ld: /usr/local/lib/gcc/x86_64-unknown-netbsd8.99/9.0.0/crtbegin.o:
relocation R_X86_64_32 against hidden symbol `__TMC_END__' can not be used when
making a shared object
/usr/bin/ld: /usr/local/lib/gcc/x86_64-unknown-netbsd8.99/9.0.0/crtend.o:
relocation R_X86_64_32 against `.ctors' can not be used when making a shared
