C++ compiler -nostdnew command option - not available (CrUn329)

Problem description

The C++ compiler -nostdnew command option is supported on Tru64 UNIX but not on HP-UX.

The -nostdnew C++ compiler command option generates calls to the pre-ANSI new implementation; this is the default when compiling -std arm, -std cfront, and -std ms. On memory allocation failure, the ANSI implementation throws std::bad_alloc while the pre-ANSI implementation returns 0.

Identifiers

-nostdnew

Solution description

Please review your code for cases that depend on this option, and use the pseudocode example provided to assist in modifying your code to work on HP-UX.

New behavior

The following pseudocode example is provided to assist you in modifying your code to adhere to the ANSI implementation of new:

Old style:

  int *i = new int;
  if (i) {
     // use i...
  } else {
     // recover from failure to allocate i ...
  }

Standard style:

  try {
    int *i = new int;
    // use i...
  }
  catch () {
    // recover from failure to allocate i ...
  }

The following example shows how to use the old style in a standard compiler without -nostdnew:

  int *i = new(std::nothrow) int;
   if (i) {
     // use i...
  } else {
     // recover from failure to allocate i ...
  }
