hi,
I have made a small C program that make use of malloc and free for processing bitmap images. when i try to run the program, I am getting a error something like
*** glibc detected *** free(): invalid next size (normal): 0x0000000000503e70 ***
I am not sure of which free() is causing this... (1 Reply)
when i try to use the class i wrote, i either get this:
*** glibc detected *** double free or corruption: 0x40236ff4 ***
and the proccess exits with an error code of 0;
or it segfaults. could someone look at my header file (with imp.) to give me some insight as to why its not working?

I am using a structure defined as follows
struct gene_square
{
double *x;
double *y;
};I have class, with a member function which is a pointer of this type:
gene_square* m_Genes;I am allocating memory in the constructors like this:
m_Genes = new gene_square;
for (ii=0;... (1 Reply)
there seems not to be error in this segment. In some computers, it can work well. But in others, it will give a failure.
why it ocurrs and how to deal with it?
in a function:
if( *ver == NULL ) {
*ver = (vertex *) malloc(sizeof(vertex)); //this line

Hi,
I am having a hell of a time getting this to work. So basically, I have opened a popen to run a program that is going to prompt an action to occur half way through, when it gets to this I need to create a separate process and do some stuff, then return to the original process. This works... (0 Replies)

Hello.
I'm looking for a quite "interesting" bug I'm using fortran 90, compiler gfortran and the main idea is for every time step I build a bin structure for search contact between particles, for this at the begining

I am facing a problem of memory corruption. The loop runs for the first time but does not go through the second time. What could be the problem?
for(int z=0;z<2;z++)

/*do something which reads this file into a 2D array*/
fclose(fp);

tau_get_event_vals
TAU_GET_EVENT_VALS(3) TAU Instrumentation API TAU_GET_EVENT_VALS(3)NAME
TAU_GET_EVENT_VALS - Gets user event data for given user events.
SYNOPSIS
C/C++:
TAU_GET_EVENT_VALS(const char **inUserEvents, int numUserEvents, int **numEvents, double **max, double **min, double **mean,
double **sumSqe);
DESCRIPTION
Retrieves user defined event data for the specified user defined events. The list of events are specified by the first parameter
(eventList) and the user specifies the number of events in the second parameter (numUserEvents). TAU returns the number of times the event
was invoked in the numUserEvents. The max, min, mean values are returned in the following parameters. TAU computes the sum of squares of
the given event and returns this value in the next argument (sumSqe).
EXAMPLE
C/C++ :
const char **eventList;
int numEvents;
TAU_GET_EVENT_NAMES(eventList, numEvents);
cout << "numEvents: " << numEvents << endl;
if (numEvents > 0) {
int *numSamples;
double *max;
double *min;
double *mean;
double *sumSqr;
TAU_GET_EVENT_VALS(eventList, numEvents, numSamples,
max, min, mean, sumSqr);
for (int i=0; i<numEvents; i++) {
cout << "-------------------
";
cout << "User Event: " << eventList[i] << endl;
cout << "Number of Samples: " << numSamples[i] << endl;
cout << "Maximum Value: " << max[i] << endl;
cout << "Minimum Value: " << min[i] << endl;
cout << "Mean Value: " << mean[i] << endl;
cout << "Sum Squared: " << sumSqr[i] << endl;
}
}
}
