The problem is that compiler forgets to call malloc and forgets to check the return value (see case17.s) and it also forgets to initialize pointer called color. That is we do not see the following lines reflected in the assembly output: char **const colorTable = (char **)std::malloc(ncolors*sizeof*colorTable), **volatile color=colorTable; if(colorTable); else { return *oldct = 0; } -- Summary: G++ 4.1.1 forgets to allocate memory (skips part of user code) Product: gcc Version: 4.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: satyaakam at yahoo dot co dot in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31048
