memory management - gfortran Deallocation segmentation fault -

-

compiling gfortran, produces 4 'ok':

  type typethree      integer      real*8      real*8, allocatable :: aa(:)   end type typethree    type typetwo       type(typethree), allocatable :: b   end type typetwo    type typeone      type (typetwo), allocatable :: c(:)   end type typeone    type(typeone), allocatable :: d(:)    allocate(d(2))   print *, 'ok'   deallocate(d)   print *, 'ok'   allocate(d(2))   print *, 'ok'   allocate(d(1)%c(2))   print *, 'ok'   deallocate(d(1)%c)   print *, 'ok'    end

and produces segmentation fault when trying deallocate d(1)%c. using ifort, resolves issue. removing integer i under typethree resolves issue. letting compiler deallocation (commenting out deallocate(d(1)%c)) resolve issue. idea appreciated. using 

ulimit -s unlimited

doesn't help.

also: 

$ gfortran -v  using built-in specs. collect_gcc=gfortran collect_lto_wrapper=/usr/lib/gcc/x86_64-linux-gnu/4.6/lto-wrapper target: x86_64-linux-gnu configured with: ../src/configure -v --with-pkgversion='ubuntu/linaro 4.6.3-1ubuntu5' --with-bugurl=file:///usr/share/doc/gcc-4.6/readme.bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --program-suffix=-4.6 --enable-shared --enable-linker-build-id --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.6 --libdir=/usr/lib --enable-nls --with-sysroot=/ --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --enable-gnu-unique-object --enable-plugin --enable-objc-gc --disable-werror --with-arch-32=i686 --with-tune=generic --enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu thread model: posix gcc version 4.6.3 (ubuntu/linaro 4.6.3-1ubuntu5)

it bug gfortran (until gfortran 4.6 included), upgrade compiler 4.7 or higher version , problem should disapear.

i'm in process of developing wp8 app makes use of background location tracking abilities provided os. idea monitor users position , notify them when near types of places. so far seems work fine , when running location tracking works expect. the problem is, seems phone times out background apps after around 4 hours, stopping location tracking. i can understand why microsoft did it, preserve battery life etc. there's not point having background location tracking app has manually restarted every 4 hours! if user chooses run app , made aware of potential battery hit, surely should able run indefinitely - point of course, if system runs out of resources or similar that's fair enough. does have experience this? there must hundreds of others apps in store have run issue have thought? , presumably there must way of keeping location tracking running? i've tried periodically updating live tile (using dispatchertimer) while tracking running doesn't seem enough ke

this code should make element disappear list when dropped on element (called cookiemonster) addevent(cookiemonster, 'drop', function (e) { if (e.stoppropagation) e.stoppropagation(); var el = document.getelementbyid(e.datatransfer.getdata('text')); el.parentnode.removechild(el); return false; }); create auxiliar variable this addevent(cookiemonster, 'drop', function (e) { if (e.stoppropagation) e.stoppropagation(); var el = document.getelementbyid(e.datatransfer.getdata('text')); var aux = el.parentnode; aux.removechild(el); return false; });
