Barker <b.w.barker at gmail dot com> 2012-06-06 20:19:57 UTC --- I found that the following nested deallocation program still fails in 4.6.3. Sorry it's so long, I don't have time to think about how to shorten it right now. It compiles and runs without error with ifort 12.1.4 20120410, and I didn't try it with 4.7. $ gfortran --version GNU Fortran (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 ... $ uname -a Linux hostname 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ gfortran testdealloc.F90 $ ./a.out *** glibc detected *** ./a.out: double free or corruption (top): 0x0000000001edb0a0 *** ======= Backtrace: ========= /lib/x86_64-linux-gnu/libc.so.6(+0x7e626)[0x7fadbf3b1626] ./a.out[0x400fa7] ./a.out[0x401029] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xed)[0x7fadbf35476d] ./a.out[0x400709] ======= Memory map: ======== 00400000-00402000 r-xp 00000000 08:05 132394 /home/barker/sandbox/a.out 00601000-00602000 r--p 00001000 08:05 132394 /home/barker/sandbox/a.out 00602000-00603000 rw-p 00002000 08:05 132394 /home/barker/sandbox/a.out 01ed8000-01ef9000 rw-p 00000000 00:00 0 [heap] 7fadbebed000-7fadbec02000 r-xp 00000000 08:05 7340318 /lib/x86_64-linux-gnu/libgcc_s.so.1 7fadbec02000-7fadbee01000 ---p 00015000 08:05 7340318 /lib/x86_64-linux-gnu/libgcc_s.so.1 7fadbee01000-7fadbee02000 r--p 00014000 08:05 7340318 /lib/x86_64-linux-gnu/libgcc_s.so.1 7fadbee02000-7fadbee03000 rw-p 00015000 08:05 7340318 /lib/x86_64-linux-gnu/libgcc_s.so.1 7fadbee03000-7fadbeefc000 r-xp 00000000 08:05 7340241 /lib/x86_64-linux-gnu/libm-2.15.so 7fadbeefc000-7fadbf0fb000 ---p 000f9000 08:05 7340241 /lib/x86_64-linux-gnu/libm-2.15.so 7fadbf0fb000-7fadbf0fc000 r--p 000f8000 08:05 7340241 /lib/x86_64-linux-gnu/libm-2.15.so 7fadbf0fc000-7fadbf0fd000 rw-p 000f9000 08:05 7340241 /lib/x86_64-linux-gnu/libm-2.15.so 7fadbf0fd000-7fadbf132000 r-xp 00000000 08:05 393626 /usr/lib/x86_64-linux-gnu/libquadmath.so.0.0.0 7fadbf132000-7fadbf331000 ---p 00035000 08:05 393626 /usr/lib/x86_64-linux-gnu/libquadmath.so.0.0.0 7fadbf331000-7fadbf332000 r--p 00034000 08:05 393626 /usr/lib/x86_64-linux-gnu/libquadmath.so.0.0.0 7fadbf332000-7fadbf333000 rw-p 00035000 08:05 393626 /usr/lib/x86_64-linux-gnu/libquadmath.so.0.0.0 7fadbf333000-7fadbf4e6000 r-xp 00000000 08:05 7340313 /lib/x86_64-linux-gnu/libc-2.15.so 7fadbf4e6000-7fadbf6e5000 ---p 001b3000 08:05 7340313 /lib/x86_64-linux-gnu/libc-2.15.so 7fadbf6e5000-7fadbf6e9000 r--p 001b2000 08:05 7340313 /lib/x86_64-linux-gnu/libc-2.15.so 7fadbf6e9000-7fadbf6eb000 rw-p 001b6000 08:05 7340313 /lib/x86_64-linux-gnu/libc-2.15.so 7fadbf6eb000-7fadbf6f0000 rw-p 00000000 00:00 0 7fadbf6f0000-7fadbf804000 r-xp 00000000 08:05 393401 /usr/lib/x86_64-linux-gnu/libgfortran.so.3.0.0 7fadbf804000-7fadbfa04000 ---p 00114000 08:05 393401 /usr/lib/x86_64-linux-gnu/libgfortran.so.3.0.0 7fadbfa04000-7fadbfa05000 r--p 00114000 08:05 393401 /usr/lib/x86_64-linux-gnu/libgfortran.so.3.0.0 7fadbfa05000-7fadbfa07000 rw-p 00115000 08:05 393401 /usr/lib/x86_64-linux-gnu/libgfortran.so.3.0.0 7fadbfa07000-7fadbfa29000 r-xp 00000000 08:05 7340317 /lib/x86_64-linux-gnu/ld-2.15.so 7fadbfc04000-7fadbfc08000 rw-p 00000000 00:00 0 7fadbfc26000-7fadbfc29000 rw-p 00000000 00:00 0 7fadbfc29000-7fadbfc2a000 r--p 00022000 08:05 7340317 /lib/x86_64-linux-gnu/ld-2.15.so 7fadbfc2a000-7fadbfc2c000 rw-p 00023000 08:05 7340317 /lib/x86_64-linux-gnu/ld-2.15.so 7fff13969000-7fff1398b000 rw-p 00000000 00:00 0 [stack] 7fff139d5000-7fff139d6000 r-xp 00000000 00:00 0 [vdso] ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0 [vsyscall] Aborted (core dumped) module class_Foo implicit none type :: SubFoo integer :: num end type type :: Foo class(SubFoo), allocatable :: aSubFoo end type Foo type :: SuperFoo type(Foo), allocatable, dimension(:) :: foos end type end module class_Foo program testdealloc use class_Foo implicit none type(SuperFoo) :: mySuperFoo type(Foo), allocatable, dimension(:) :: myFoos type(SubFoo) :: mySubFoo mySubFoo=SubFoo(1) allocate(myFoos(10)) allocate(myFoos(1)%aSubFoo, source=mySubFoo) mySuperFoo = SuperFoo(myFoos) deallocate(mySuperFoo%foos) end program testdealloc
