Now call:

-xlazyload -s usr/src/lib/libc/port/threads/plockstat.d
and please report the cpp command line you see from this command.

-D__amd64 -D__SUNW_D_VERSION=0x0100c001 -D__STDC__=0 /dev/fd/3 /dev/fd/4
OK, I get this:
-D__sun -D__unix -D__SVR4 -D__SUNW_D=1 -D__SUNW_D_64 -D__SunOS_5_11
-D__i386 -D__SUNW_D_VERSION=0x01006003 -D__STDC__=0
and it seems that the main difference is -D__i386 vs. -D__amd64.
Given the fact that -32 instructs dtrace to compile for a 32 bit target,
-D__amd64 seems to be incorrect.
I do not understand this...

The original comman I've traced was LD_PRELOAD=/tmp/libdtrace.so.1
/usr/sbin/amd64/dtrace -xnolibs -G -64 -C -s
usr/src/lib/libc/port/threads/plockstat.d , so __amd64 is expected.
But what is not is the diff. Are you sure that /dev/fd/3 is
usr/src/lib/libc/port/threads/plockstat.d ? diff doesn't show anything
related to int8_t...
Are you sure that /dev/fd/3 is
