Bug 1271398

Created attachment 1082621 [details]
screenshot of the correct result.

Description of problem:

After updating to RHEL 6.7, one of my frequently used tools stopped working.

Version-Release number of selected component (if applicable):

Previous 6.6, current 6.7

How reproducible:

download "SU 44 Full Source Code" from http://www.cwp.mines.edu/cwpcodes/. uncompress and untar the compressed tarfile, then go to directory "src" and
Compile the code according to the installation guide.

Steps to Reproduce:
1. generate a binary data file with the following C++ code:
=========================================

#include <stdlib.h>
#include <stdio.h>

int main()
{
    float value[10000];

    FILE *fp = fopen("test.dat", "wb");

    for (int i = 0; i < 10000; i++)
        value[i] = i;

    fwrite(value, sizeof(float), 10000, fp);

    fclose(fp);
    return 0;
}
=========================================

2. run "/your_installation_path/xcontour n1=100 < test.dat"
3. a window popped out with contour displayed if under RHEL 6.6 but no contour displayed if under RHEL 6.7 (even when the executable is complied under RHEL 6.7).


Actual results: only popped out a window (see attached "snapshot_RHEL6.7.png", which looks like a snapshot of some parts of other windows).


Expected results:popped a window with contour displayed (see attached "snapshot_RHEL6.6.png").


Additional info:

I am sorry that the duplication procedures are not simple. Please contact me if you need any help!


Thank you,
