Bug #: 55469
Summary: memory leak on read with istat.ne.0
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: joost.vandevond...@mat.ethz.ch
The following testcase leads to memory leaks with gfortran 4.5/4.6/4.7/4.8 (as
found by valgrind) 4.1 seems not to leak (but has a couple of warnings).
REAL :: z
INTEGER :: istat
CHARACTER(LEN=3) :: t
t="NVE"
READ (UNIT=t,FMT=*,IOSTAT=istat) z
END
note that istat.NE.0 in this case.
