Does this still occur with 0.96?

That error is probably coming from here (in pdf.c):
p = buf = mmap(NULL, size, PROT_READ, MAP_PRIVATE, desc, offset);
if(buf == MAP_FAILED) {
cli_errmsg("cli_pdf: mmap() failed\n");
return CL_EMAP;
}
Please change that code to be:
p = buf = mmap(NULL, size, PROT_READ, MAP_PRIVATE, desc, offset);
if(buf == MAP_FAILED) {
perror("mmap failed");
cli_errmsg("cli_pdf: mmap() failed\n");
return CL_EMAP;
}
So that we see the actual error.
Does this occur every time you scan that file?
If so, please open a bugreport, and attach the log from this command:
$ strace clamscan
/var/spool/MIMEDefang/mdefang-o38GNjZv088151/Work/msg-81178-1234.pdf 2>log
Assuming you run a FreeBSD that supports strace, if not use ktrace
instead of strace, and attach the output from kdump.
Best regards,
