making valgrind abort on error for heap corruption checking?

Question
I'd like to try using valgrind to do some heap corruption detection. With the following corruption "unit test":
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
int main()
{
char * c = (char *) malloc(10) ;
memset( c, 0xAB, 20 ) ;
printf("not aborted\n") ;
return 0 ;
}
I was suprised to find that valgrind doesn't abort on error, but just produces a message:
valgrind -q --leak-check=no a.out ==11097== Invalid write of size 4 ==11097== at 0x40061F: main (in /home/hotellnx94/peeterj/tmp/a.out) ==11097== Address 0x51c6048 is 8 bytes inside a block of size 10 alloc'd ==11097== at 0x4A2058F: malloc (vg_replace_malloc.c:236) ==11097== by 0x400609: main (in /home/hotellnx94/peeterj/tmp/a.out) ... not aborted
I don't see a valgrind option to abort on error (like gnu-libc's mcheck does, but I can't use mcheck because it isn't thread safe). Does anybody know if that is possible (our code dup2's stdout to /dev/null since it runs as a daemon, so a report isn't useful and I'd rather catch the culprit in the act or closer to it).
No correct solution
