Summary: different code behaviour with -fprofile-arcs -ftest-
coverage
Product: gcc
Version: 3.2.3
Status: UNCONFIRMED
Severity: critical
Priority: P2
Component: c++
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: lothar at xcerla dot com
CC: gcc-bugs at gcc dot gnu dot org
lothar@janus$ gcc --version
gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

PURPOSE.
The code behaviour is different if I compile with -fprofile-arcs
-ftest-coverage or not. In both cases I compiled with -O0 (no
optimizations). I noticed it, as some of my cppunit tests failed. Here
is one of the tests: It basically only stores a value in a class which
acts as a wrapper to the GNU MP library and get's the same value back.
To my surprise the value I get back is both, the same and not the same
as I put in (at least according to the C++ comparison operators
available).
void gccbug ( void )
{
{
signed long const c_v(5);
RawInteger i(c_v);
signed long const c_v2(i.valueSignedLong());
std::cout << "long " << std::endl
<< c_v2 << " "
<< c_v << " "
<< (c_v2 > c_v) << " "
<< (c_v2 >= c_v) << " "
<< (c_v2 < c_v) << " "
<< (c_v2 <= c_v) << " "
<< (c_v2 == c_v) << " "
<< (c_v2 != c_v) << " "
<< std::endl;
}
{
double const c_v(5.0);
RawInteger i(c_v);
double const c_v2(i.valueDouble());
std::cout << "double " << std::endl
<< c_v2 << " "
<< c_v << " "
<< (c_v2 > c_v) << " "
<< (c_v2 >= c_v) << " "
<< (c_v2 < c_v) << " "
<< (c_v2 <= c_v) << " "
<< (c_v2 == c_v) << " "
<< (c_v2 != c_v) << " "
<< std::endl;
}
}
Here's the output of this code fragment:
without code coverage:
long
5 5 0 1 0 1 1 0
double
5 5 0 1 0 1 1 0
with code coverage:
long
5 5 0 1 0 1 1 0
double
5 5 0 1 0 1 0 1

I also cannot reproduce this on `gcc version 3.2.1 20021207 (Red Hat Linux 8.0 3.2.1-2)'.

I could reproduce it under 3.3.1 (20030707) but the problem is that gcc is using
excessive precission for the floating point so this is not a bug (actually this is a dup of bug
323).

Is this really a duplicate? I read the description to 323 and it seemed it is due to optimization
switched on. I used -O0, therefore there should be NO optimization at all. And it shoes up
ONLY with the -fprofile-arcs -ftest-coverage switch. Is this really the same origin?

I tried to compile the code with -ffloat-store as suggested in bug 323. It has NO effect on this
bug. Therefore I reopen the bug.

It still is a dup of 323 because the problem is that the store happens so that 5.0 does not equal to
5.0 and the options -fprofile-arcs -ftest-coverage just force the store to happen that would not
over-wise happen. Also you are comparing by using equals which is never going to be the same
with floating point.

I prepared an additional case, this time with unsigned long rather than double. This should
make clear that the bug is with -fprofile-arcs -ftest-coverage and not floating point related.
I will attach the preprocessed file like for the first case.

Okay the problem is not per say with -fprofile-arcs -ftest-coverage but with -fnon-call-
exceptions and -fprofile-arcs.
I can confirm this on the mainline (20030804) Here is the reduced source but I could not
remove the dependent on string:
#include <string>
typedef unsigned long ACE_UINT32;
extern "C" void abort();
static ACE_UINT32 const msc_maxCurrencyID = 9999;
class ResourceBalanceType2
{
public:
explicit ResourceBalanceType2(
ACE_UINT32 resourceBalanceTypeID,
ACE_UINT32 isoValue,
const std::string& rc_shortName,
const std::string& rc_symbol
);
public:
const ACE_UINT32 mc_resBalTypeID;
const ACE_UINT32 mc_isoValue;
const std::string mc_shortName;
const std::string mc_symbol;
};
void f(){}
ResourceBalanceType2::ResourceBalanceType2(
ACE_UINT32 resourceBalanceTypeID,
ACE_UINT32 isoValue,
const std::string& rc_shortName,
const std::string& rc_symbol
): mc_resBalTypeID(resourceBalanceTypeID),
mc_isoValue(isoValue),
mc_shortName(rc_shortName),
mc_symbol(rc_symbol)
{
bool isGreater = (mc_isoValue > msc_maxCurrencyID);
f();
bool temp = mc_isoValue > msc_maxCurrencyID;
if(!isGreater) abort();
if(!temp) abort();
}
int main ( int argc, char * argv[] )
{
ACE_UINT32 const mc_isoValue = 10000;
ResourceBalanceType2 rbResourceBalanceType2(3, mc_isoValue, "ATM", "M");
