Bug ID: 95948
Summary: memmove error
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: Khram at mail dot ru
Target Milestone: ---
Memmove has a mistake. Need like this:
char* memmove( char *A, char *B, int L ) //! странности из GCC-10.1
{ char *res=A; if( A>B )while( L-->0 )*A++=*B++; else
{ A+=L; B+=L; while( L-->0 )*--A=*--B; } return res;
}
