openCL clCreateProgramWithBinary generates munmap_chunk() error inside a C++ program -

i´m trying fpga altera opencl libraries have use soc opencl. have cross compile application , have done. in fact software has many parts , it´s bit difficult follow. fact if cross compile alone opencl code working program. when insert code inside program munmap_chunk error can´t understand. when use gdb received error when line executed:

program = clcreateprogramwithbinary(context, 1, &device, (const size_t *)&binary_size, (const unsigned char **)&binary_buf, &binary_status, &status_ocl);

returns error: *** error in `../../bin/linux-arm/hpsfpga1dtest': munmap_chunk(): invalid pointer: 0x00294a98 *****

so can´t info reason why happening. code being executed (i can show function init, code longer).

what have done execute program valgrind. gives info, problem don´t quite understand it. valgrind show errors don´t know how fix them. attach valgrind output. ask understanding valgrind in order fix memory issue. lot help!!

here output of valgrind. part think it´s more important , don´t understand is:
