Ok , so I put my code in a script and run valgrind as follows:
$ cat foo.sh
#!/bin/sh
while [ 1 ]; do uptime && free && sleep 1; done
$ valgrind --tool=memcheck --error-exitcode=1 ./foo.sh
It tooks me about 1 hour to reproduce it and I got this.

Segmentation fault
Which seems not very useful but the SIGSEGV seems to be again in sleep first?
Should I run valgrind with any other parameters?
Any ideas on this?
Thanks in advance for your time.
