SIGBUS bus error

tommy_28 — Thu, 05 Feb 2004 04:41:07 GMT

Running a CPP compiled file under hpux11.23 got core dump. Use gdb to debug , showed below error msgs:

Program received signal SIGBUS, Bus error (si_code: 1).
0x40000000000c02b0:0 in CRuntimeData::CRuntimeData (this=0x6000000000008c6c)
at ../src/runtimedata.cpp:36
36 CRuntimeData::CRuntimeData()

runtimedata.cpp:36 is:
CRuntimeData::CRuntimeData()
{
/*
pthread_mutex_init(&m_mutexLock,NULL);
pthread_mutex_init(&m_mutexTmpLock,NULL);
pthread_cond_init(&m_mutexCondVariable,NULL);
*/
printf("nCRuntimeData=%d\n",nCRuntimeData);

nCRuntimeData++;
}

What's wrong with this program?
Thanks!

What is the definition of nCRuntimeData?

It seems to me that's where the problem is... And that line 36 is the printf (please confirm). Though it could be the increment line as well.

A SIGBUS is often caused by accessing data at an address that is not aligned to a multiple of the width of the data. A 4 byte int must be aligned on a multiple of 4. An 8 byte long must be aligned on a multiple of 8.

From the limited information available, I would guess that nCRuntimeData is a long and a member of the CRuntimeData class. It may be that CRuntimeData::CRuntimeData was called using a bad pointer to an instance of CRuntimeData. The 'this' address reported by gdb is only aligned on a multiple of 4 bytes. That could happen if the 'new' operator had been redefined with a function that returned addresses with insufficient alignment. It could also be caused by replacing malloc.
