[Valgrind-users] Making valgrind output diff-friendly

[Nick S. <sa...@ya...>]

Hi all,

Valgrind's typical output


==19182== Invalid write of size 4 

==19182==    at 0x804838F: f (example.c:6) 

==19182==    by 0x80483AB: main (example.c:11) 

==19182==  Address 0x1BA45050 is 0 bytes after a block of size 40 alloc'd 

==19182==    at 0x1B8FF5CD: malloc (vg_replace_malloc.c:130) 

==19182==    by 0x8048385: f (example.c:5) 

==19182==    by 0x80483AB: main (example.c:11)

is not very diff-friendly. Is there a way to suppress process id and address printing? Perhaps something like

==?????== Invalid write of size 4
==?????==    at 0x???????: f (example.c:6)
==?????==    by 0x???????: main (example.c:11)
==?????==  Address 0x??????? is 0 bytes after a block of size 40 alloc'd
==?????==    at 0x???????: malloc (vg_replace_malloc.c:130)
==?????==    by 0x???????: f (example.c:5)
==?????==    by 0x???????: main (example.c:11)


or
==== Invalid write of size 4
====    at : f (example.c:6)
====    by : main (example.c:11)
====  Address  is 0 bytes after a block of size 40 alloc'd
====    at : malloc (vg_replace_malloc.c:130)
====    by : f (example.c:5)
====    by : main (example.c:11)


Or is there a better way?

Thanks,
Nick
