Hello:
My application work without using valgrind, but when I use valgrind 390 with my
application, the application crash soon after start:
==25545== Process terminating with default action of signal 11
(SIGSEGV): dumping core
==25545== Access not within mapped region at address 0x86C006000

==25545== by 0x529E74C: clone (in /lib64/libc-2.4.so)
==25545== If you believe this happened as a result of a stack ==25545==
overflow in your program's main thread (unlikely but ==25545== possible), you
can try to increase the size of the ==25545== main thread stack using the
--main-stacksize= flag.
==25545== The main thread stack size used in this run was 16777216.
==25545==
The stack trace seems like the Bug 95667 reported in 2004. I think the bug has
been already solved. But why it happened again for me?
My application's code as below:
resourcedetect.cpp:647
647: if ( MEM_INFO_RECORDS_ITEM_NUM != sscanf(m_arrArray4TempBuff,
648: "%s %llu",
649: m_arrCurTotalMemInfo[i].name,
650: &m_arrCurTotalMemInfo[i].value))
The type of m_arrCurTotalMemInfo[i].name is char[], And the type of
m_arrCurTotalMemInfo[i].value is int8, so I think there is no bug in my
application.
Anyone could help me?
