Thanks Chad, but I don't think that this is the problem. The this->rAcqArr
points to the beginning of an array in the traced process. I initialize it in
a previous clause that has exactly the same probe:
pid$target::ReportTx:entry
/arg1 != 0 /
{
this->dataP = (ProfData*)copyin(arg2, sizeof(ProfData));
this->numEntries = this->dataP->numRAcqEntries;
this->rAcqArr = this->dataP->racqInfoArr;
}
So the value of this->rAcqArr should be live until all clauses with the same
probe are done executing.
Moreover, I know that the value that I'm getting is valid, because I had the
following printf statement:
pid$target::ReportTx:entry
/arg1 != 0 && this->numEntries != 0/
{
printf("NumEntries: %lld\n", (long long)this->numEntries);
this->entry =
(ReadAcqEntry*)copyin((uintptr_t)&(this->rAcqArr[this->numEntries-1]),
sizeof(ReadAcqEntry));
this->pcInt = (uintptr_t)(this->entry->pc);
/* this->instr = stringof(this->pcInt);*/
printf("%p\t%d\t%d\t%d\n",
this->entry->pc,
this->entry->acqNum,
this->entry->upgradeNum + this->entry->contUpgradeNum,
this->entry->contUpgradeNum);
this->numEntries--;
}
and the results look fine. The only problem is when I un-comment the stringof
statement.
I even tried using this->entry->pc as a key to an aggregation, with no
problems. I only encountered the problem when I tried to convert it to a
string.
So, I can printf this->entry->pc (with %p flag), I can use it as a key to an
aggregation, but I cannot convert it to a string --- any idea why?
As an aside, I noticed that the invalid address specified in the error message
is different that the value of this->entry->pc.
Thanks again,
Yossi
