Introduction

When new runs out of memory, I get a call to abort or an exception.

I want it to return NULL.

Possible solution

Use the nothrow variant of new as illustrated in provided Screen dumps and Example ProjectExample IAR Embedded Workbench for ARM 7.20.zip.

Background

See section USING NEW HANDLERS in the compiler guide, for example "IAR C/C++ Development Guide" for ARM (page 186 in Part number: DARM-12), for related info.
