Bug ID: 15852
Summary: strdup(NULL) causes SEGV
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: arno at cs dot vu.nl
CC: drepper.fsp at gmail dot com
There is no checking of the input value, 2.18 just does:
size_t len = strlen (s) + 1;
as its first line. Is this correct / by design?
Thanks,
Arno
