Valgrind is throwing error "failed in UME with error 22 (Invalid argument)."

Hi Friends,

We suspect some memory leaks in our program and thought to debug them with valgrind. But when running with valgrind it threw the following error.

Code:

Code:

[root@SCE10000 pkgout]# valgrind ./bin/fp_fd
valgrind: mmap(0x6c2000, 1440247808) failed in UME with error 22 (Invalid argument).
valgrind: this can be caused by executables with very large text, data or bss segments.

If we see the size command output on ./bin/fp_fd

Code:

[root@SCE10000 pkgout]# size bin/fp_fd
   text    data     bss     dec     hex filename
781670    9832 1440248260      1441039762      55e48592        bin/fp_fd

I surfed over internet for this, but couldn't find any solution.

Can anybody please suggest how to make my program to run with valgrind.

Or please suggest any other memory leak profiling tools.
Thanks in Advance,
Vamsi Krishna.

It is in 64-bit mode, I suppose?

BTW: your bss being 1.5 GiB is intentional? (I would use dynamic allocation instead of static data.)
