dtrace discuss - Oct 2007 - strange problem on SXDE3

Strange problem on a desktop, 64 bit, SXDE3.

] ./jpg1.d
dtrace: failed to compile script ./jpg1.d: "/usr/lib/dtrace/iscsi.d",
line 94: syntax error near "uiscsiproto_t"

Doesn''t matter what script. Even classic oneliners such as:
] dtrace -n ''syscall::open*:entry { printf("%s %
s",execname,copyinstr(arg0)); }''

bomb in this way...

dtrace: invalid probe specifier syscall::open*:entry { printf("%s %
s",execname,copyinstr(arg0)); }: "/usr/lib/dtrace/iscsi.d", line
94:
syntax error near "uiscsiproto_t"

Thing is, I have another machine (a laptop, 32 bit) that works
perfectly. The iscsi.d file is identical on both.

Ideas?

Hi Francois,

You''re hitting this bug:

  6581257 dtrace_lookup_by_type() can fail spuriously

It existed in DTrace pretty much since the beginning, but we only started
hitting it after the iSCSI target provider integrated. The bug was fixed
in build 72.
