Core dump on HP-PA RISC

porwaa — Tue, 14 Apr 2009 15:06:23 GMT

I'm having a core dump on HP-PA RISC for which I'm attaching the back trace.
The code which produces this is as below and the crash occurs at the line object.insertKeyAndValue.
(1) Do we have to have some necessary pathces.
(2) Is this a memory issue. How to find if this is so?

int IR_rawMessage::init()
{

// Populate a hash table of message types

try
{

static Lock critSection;

{
AutoLock auto_lock (critSection);

if (o_msgDictionary.isEmpty())
{

object.insertKeyAndValue(new String(IR_M),
new IR_m_A());

Without disassembly and a register dump, there isn't much we can tell from your stack trace.
(gdb) info reg
(gdb) disas $pc-4*16 $pc+4*4

You could have a thread stack overflow. You can check by:
(gdb) p /x $sp_save = $sp
(gdb) frame 11
(gdb) p $sp - $sp_save

(What version of gdb are you using?)
