|Priority||normal||Severity||minor||Reproducibility||have not tried|
|Target Version||0.9.9||Fixed in Version|
|Summary||0000531: Deallocation error in importhandler.c:476|
|Description||Not sure if this is a 64-bit Windows issue, or more generally appears anytime when you build the installed binaries with MALLOC_DEBUG turned on via SCons.|
The error is "ascfreef called on a deallocated piece of memory. Called from file: ascend\compiler\importhandler.c on line 476".
The same error comes from lines 374.
There is another error "malloc returned a piece of memory that is already being used. Called from ascend\utilities\ascEnvVar.c on line 518."
The test file that showed this was models/johnpye/fprops/combinedcycle_fprops.a4c in the FPROPS2 branch at changeset 4033, but it possibly/probably appears with this and other files in the trunk branch, needs to be tested.
|Tags||No tags attached.|
||nearly anything reported by malloc_debug (certainly a double free) should be shown by valgrind under linux as well without malloc_debug turned on.|
Email from: John Pye <firstname.lastname@example.org>
I think that part of what was happening here was that I had out-of-sync
binaries, some with MALLOC_DEBUG on, and some with it off. After fixing
that and breaking it down more, I'm on to http://ascend.org/b576 which
seems far more puzzling to me.
I'd welcome your suggestions on how to fix that.
