Question

The system has only 128 MB ram and I couldn’t successfully run valgrind, it will just run out of memory and too slow to be usable. The processor is also very slow.

Is there a simpler tool on PPC32 to check for heap corruption/leaks for PPC 32 with very limited resource?

I am thinking maybe something small like libsegfault.so that can be used with LD_PRELOAD , but to check for malloc/free problems?

Answer 1

Electric Fence is ideal for this use case (and does leverage LD_PRELOAD, can be combined with libsegfault.so).

In addition to efence, you can use other features, some of which will end up costing cycles and/or additional memory overhead (though still likely significantly less than valgrind):

• gcc‘s mudflaps
• gcc‘s fortify-source
• glibc‘s mcheck(), MALLOC_CHECK_
• clang‘s address sanitizer
