Name

wrapalloc - Wraps up glibc's memory allocation and freeing API functions to ease dynamic tracing

Synopsis

LD_PRELOAD=/path/to/wrapalloc/wrapalloc.so your_app

Description

The glibc binaries shipped with most mainstream Linux distributions usually suffer from the incorrect debuginfo generated by gcc under very aggressive optimizaton flags.

This LD_PRELOAD library wraps up the common glibc API functions for memory allocations and de-allocations so that dynamic tracing tools like those based on systemtap can work reliably.

Building
