Here's another cpp buglet on Leopard. Basically, using cpp
underneath dtrace doesn't yield the same results as using it
separately. I have posted this bug as ADC Bug ID # 5611720.
% cat bug_1
/* bug_1 - demonstrate cpp(1) buglet */
#pragma D option quiet
#define BEG_0(code) printf("code={\n")
#define END_0 printf("}\n")
#define PDN_2(na, name) printf(" na=%d\n", name)
profile:::tick-1sec {
BEG_0(tt);
PDN_2(ts, timestamp); /* timestamp (DTrace variable) */
END_0;
}
% sudo dtrace -I. -C -s bug_1
code={
na=2031174750815
}
code={
na=2032174742727
}
code={
na=2033174726501
}
^C
% cpp bug_1 > bug_1c
% cat bug_1c
# 1 "bug_1"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "bug_1"
#pragma D option quiet
profile:::tick-1sec {
printf("tt={\n");
printf(" ts=%d\n", timestamp);
printf("}\n");
}
% sudo dtrace -I. -s bug_1c
tt={
ts=2157891353951
}
tt={
ts=2158891404722
}
tt={
ts=2159891373135
}
tt={
ts=2160891368022
}
^C
