Product: PCRE
Version: 8.37
Hardware: Other
OS: Linux
Status: NEW
Severity: bug

Hello,my platform is mips64-octeon-linux-gnu;
i add register_function in pcre_global.c like this
:
PCRE_EXP_DATA_DEFN void register_pcre_malloc_fun( PCRE_MALLOC_T malloc,
PCRE_FREE_T f ree)
69 {
70 if (malloc == NULL || free == NULL)
71 {
72 return;
73 }
74 g_pcre_malloc = malloc;
75 g_pcre_free = free;
76 }
static void* LocalPcreMalloc(size_t aSize)
78 {
79 if (NULL == g_pcre_malloc)
80 {
81 printf("pcre malloc is null\r\n");
82 return NULL;
83 }
84
85 return g_pcre_malloc(aSize);
86 }
87 static void LocalPcreFree(void* aPtr)
88 {
89 if (g_pcre_free == NULL)
90 {
91 printf("pcre free is NULL\r\n");
92 return;
93 }
94 g_pcre_free(aPtr);
95 }
PCRE_EXP_DATA_DEFN void *(*PUBL(malloc))(size_t) = LocalPcreMalloc;
98 PCRE_EXP_DATA_DEFN void (*PUBL(free))(void *) = LocalPcreFree;
99 PCRE_EXP_DATA_DEFN void *(*PUBL(stack_malloc))(size_t) =
LocalPcreMalloc;
100 PCRE_EXP_DATA_DEFN void (*PUBL(stack_free))(void *) = LocalPcreFree;
101 PCRE_EXP_DATA_DEFN int (*PUBL(callout))(PUBL(callout_block) *) =
NULL;
102 PCRE_EXP_DATA_DEFN int (*PUBL(stack_guard))(void) = NULL;
103
i compile the pcre in host mips64-octeon-linux-gnu to get the lib, and before
i use pcre_compile, i register the LocalPcreMalloc with "kmalloc"
i use it in http user-agent pcap identify, when comes a http pcap with a
user-agentï¼i
use pcre_exec to matchï¼first about 6miniutes ,the return value is 0 ,never
match,but after 6miniutes ,it starts match, and get got value 9 or -1 and its
right,why the start 6miniutes return 0 in pcre_exec?
