I fixed the problem - diff --git a/cde/programs/dtcreate/UxXt.h b/cde/programs/dtcreate/UxXt.h index 76eec8a..34b3dde 100644 --- a/cde/programs/dtcreate/UxXt.h +++ b/cde/programs/dtcreate/UxXt.h @@ -170,6 +170,8 @@ extern void UxMrmRegisterClass( char *, Widget (*)(Widget, String, A /* The following are declarations of the functions in UxXt.c */ +extern void* UxNewContext (size_t size, int isSubclass); + extern int UxPopupInterface( Widget wgt, XtGrabKind grab_flag ); extern int UxPopdownInterface( Widget wgt ); extern int UxDestroyInterface( Widget wgt); Can you give me your value of UxContext after this: 1680 UxCreateActionAppShellContext = UxContext = 1681 (_UxCCreateActionAppShell *) UxNewContext( sizeof(_UxCCreateActionAppShell), False ); My value after patching: (gdb) print UxContext $1 = (_UxCCreateActionAppShell *) 0x805c13c00 without the patch rax 0x805c13c00 34456288256 is returned from the function, but it gets truncated to 32 bit value: 0x000000000040a08d <create_applicationShell1+29>: callq 0x412510 <UxNewContext> 0x000000000040a092 <create_applicationShell1+34>: movslq %eax,%rax rax 0x5c13c00 96549888 so the next address causes a fault. FreeBSD addresses on the heap don't fit into 32-bits so that's probably the reason why one can get away with many 64-bit coding problems on Linux. //Marcin ------------------------------------------------------------------------------ How fast is your code? 3 out of 4 devs don\\\'t know how their code performs in production.
