Hi :=)
Ok, I run a stack trace and have the following:
free_libblock(ListBase * 0x8c0292b0, void * 0x14040004) line 406 + 4 bytes
free_main(Main * 0x006a012c) line 528
clear_global() line 232
setup_app_data(BlendFileData * 0x008e743c, char * 0x0055f360) line 350
BKE_read_file_from_memory(char * 0x0056eda0 datatoc_B_blend, int 93008, void * 0x00000000) line 471
BIF_read_homefile() line 300 + 20 bytes
BIF_init() line 607
main(int 1, char * * 0x006a0090) line 448
WinMain(HINSTANCE__ * 0xcf554372, HINSTANCE__ * 0x00000000, unsigned short * 0x2669fed8, int 5) line 47 + 12 bytes
WinMainCRTStartup(HINSTANCE__ *, HINSTANCE__ * 0x14040004, unsigned short * 0x14040004, int 96) line 21 + 20 bytes
27f66ee0()
I run also a step by step debug. And I CRASHES my pocketpc :=) Ah... first big crash! It should happen... but what I discovered is that my pocketpc crashes in intern/mallocn.c in the function void *MEM_callocN(unsigned int len, char *str) in this command:
memh= (MemHead *)calloc(len+sizeof(MemHead)+sizeof(MemTail),1);
That's probably what I already mentioned with UNICODE. I thought it would work without big problems but of course it was wrong... especially for this memory manipulations... in unicode, character are 2 bytes... and memory allocation should consider it... all strlen() or strcmp() function should be wcslen() or wcscmp()... and also char shouldd be wchar_t, not 'a' but _T('a')...
When I began my research on pocketpc porting, I collect lot of information about this... I will have to study this again... the "simpletest.c" in guardedalloc will be a fist good exercice.
I will let you know.
