Memory Allocating Error ( I'm Massed Up )

Started by

hi I'm very exhausted for an allocating problem in my codeblocks project.

when I was running some mallocs in lvm_read app was dead.

I caught some problems looks like logical error in lvm_utility_getword. but It's still stopped running

I really don't know why ... ( I uploaded my project )

You'll probably get more/better help if you explain in more detail what your problem is and provide some of the relevant code inline instead of in a .zip file. Lots of people will just ignore your thread if you're expecting them to download, unzip, build, run and debug you entire project for you.

Have you tried running it in debug mode? It should be F8.

Remember to add debug symbols in the Settings > Compiler > Compiler settings, mark the "Produce debugging symbols [-g]" option.

You can also run it in valgrind (use "-v --track-origins=yes" options).

Currently working on a scene editor for ORX (http://orx-project.org), using kivy (http://kivy.org).

thanks for your advices :)

my source structure is

when I compiled and ran lvm_read( SrcStr , "main" ) ; fully , in code blocks it was stopped and in bin folder

it printed "what?" "%d %d %d\n" but ProcCnt , OpCnt , MemCnt had too big values... and was stopped after printing. ( I know it was caused by uninitializing but don't know why it was different between bin folder execution and codeblock running. )

if I commented out from printf( "what?\n" ) ; to above // store info comment , it was stopped....

( plus ) sorry I found a cause but I faced an error " ntdll!RtlpNtMakeTemporaryKey " at call stack in debugging

What happens here do you think? In particular when your input file is more than 256 bytes?

I would like to suggest you do smaller tests. Take a routine, and write a new main program that only calls that function, and tests whether the right result gets returned.

Do that for various routines, so you can somewhat check that the code does something useful.

That should give you a handle on locating any problem that may exist (I only briefly browsed the post, it's too much to check in detail)

btw, why are you making an assembler?

What happens here do you think? In particular when your input file is more than 256 bytes?

THANKS SO MUCH I was just foolish X( and after succeeding to debug it , I was faced at some logical error but fixed.

especially in your comment "Take a routine, and write a new main program that only calls that function, and tests whether the right result

gets" it's a great tip for debugging despite simplest thing thanks again! :D

I'm making a virtual machine so assembler is required finally:)
