Hi,
We have problems using gcc 4.1.1. we are trying to compile a code in file
case17.cpp (see attached in testcase area). The problem is that compiler
forgets to call malloc and forgets to check the return value 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; }
