Consider the following trivially simple program :
PROGRAM p IMPLICIT NONE !.. Local variables CHARACTER(LEN=2) :: StrBuffer INTEGER :: I I = 1 WRITE(StrBuffer, FMT='(I2)') I !.. STOP END PROGRAM p
When the code is compiled with Intel Fortran (version 14 or 2015 Beta) and the program is executed, Dr Memory utility indicates there is a memory leak associated with the WRITE statement. The output generated by the utility is as follows:
Dr. Memory version 1.7.0 Running "Debug\TestFor32.exe" Error #1: LEAK 12 bytes replace_malloc d:\drmemory_package\common\alloc_replace.c(2320): for__get_vm ??:0 for__acquire_lun ??:0 for_write_int_fmt ??:0 P TestFor.f90(10): main ??:0 ERRORS FOUND: 0 unique, 0 total unaddressable access(es) 0 unique, 0 total uninitialized access(es) 0 unique, 0 total invalid heap argument(s) 0 unique, 0 total GDI usage error(s) 0 unique, 0 total handle leak(s) 0 unique, 0 total warning(s) 1 unique, 1 total, 12 byte(s) of leak(s) 0 unique, 0 total, 0 byte(s) of possible leak(s) Details: C:\..\DrMemory-TestFor32.exe.4680.000\results.txt
Can someone at Intel please investigate and provide feedback on this memory leak? In one of my codes, such a WRITE operation on an internal file can occur many times and there are some performance issues with this code, hence I appreciate any clarification any one can provide.
