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 Fer
