repro
Noticed that when linked ports/sysutils/safecat-1.13
and I think I saw the same in few other ports.
Error was:
/usr/bin/ld: error: byte_copy.c:(.text+0x0): duplicate symbol 'byte_copy'
/usr/bin/ld: error: byte_copy.c:(function byte_copy): previous definition was
here
Reproduce file (attached) can be reduced to:
-o safecat
usr/ports/sysutils/safecat/work/safecat-1.13/str.a
usr/ports/sysutils/safecat/work/safecat-1.13/alloc_re.o
usr/ports/sysutils/safecat/work/safecat-1.13/byte_copy.o
and problem is that str.a contains byte_copy.o:
./makelib str.a str_len.o byte_chr.o byte_diff.o byte_copy.o byte_cr.o
byte_zero.o
and has next symbol: 'byte_copy'
So LLD first creates lazy symbol 'byte_copy', then finds undefined 'byte_copy'
in alloc_re.o and resolves it. At the end it reports duplicate symbol from
byte_copy.o.
Do we want to fix it ?</pre>
