Subject: [Bug c++/31048]  New: G++ 4.1.1 forgets to allocate memory (skips part of user code)
Date: Mon, 05 Mar 2007 17:16:00 -0000	[thread overview]
Message-ID: <bug-31048-12095@http.gcc.gnu.org/bugzilla/> (raw)

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 (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; }
