We're facing some problems with CTF on -STABLE. We need that so we can
have DTrace runing on FreeBSD 7
The tools and the libs build fine, but I can't ctfconvert anything. In
some cases get the following error:
ctfconvert -L VERSION -g tdfx_linux.o
ERROR: ctfconvert: die 37: base type without name
and in some others ctfconvert just dies and dumps core.
I all cases, xstrdup is the culprit:
(gdb) where
#0 0x281bbfa9 in strlen () from /lib/libc.so.7
#1 0x28147187 in strdup (str=0x0) at /usr/src/lib/libc/string/strdup.c:47
#2 0x08050f22 in xstrdup ()
#3 0x0804dfde in die_through_create ()
#4 0x0804d712 in die_create_one ()
#5 0x0804d769 in die_create ()
#6 0x0804ecb4 in dw_read ()
#7 0x0804c12b in main ()
now, if I copy both the .o and the ctfconvert executable to a -CURRENT
box, it runs fine.
From the error (base type without name) it seems that some info that
ctfconvert needs is not available on -STABLE, or maybe it's on a
different place or in a format ctfconvert doesn't understand. Maybe
libdwarf is built on a different way, but so far I couln't find what
the problem is.
Any pointers/help would be greatly apreciated
