Description Arfrever Frehtes Taifersar Arahesis (RETIRED) gentoo-dev 2009-05-04 03:26:24 UTC
net-libs/libproxy-0.2.3 uses implicitly declared function strdup() which causes:

 * QA Notice: Package has poor programming practices which may compile
 *            fine but exhibit random runtime failures.
 * proxy.c:50: warning: implicit declaration of function ‘strdup’

From string.h:
#if defined __USE_SVID || defined __USE_BSD || defined __USE_XOPEN_EXTENDED
/* Duplicate S, returning an identical malloc'd string.  */
extern char *strdup (__const char *__s)
     __THROW __attribute_malloc__ __nonnull ((1));

As you can see, strdup() returns 'char *', but compiler treats all implicitly declared functions as returning 'int'. It will cause segmentation fault on 64-bit architectures where sizeof(pointer) != sizeof(int).
