Re: help - SEGV_MAPERR

[Guntupalli Santhi]

Hi,

 In continuation of my previous mail since our application is a multti-threaded and 64 bit,

i  have used the "-mlp64  -D_REENTRANT -pthread" flags consistently at compile time and linking time. Because of this problem i am not able to proceed further.

Thanks in advance.

 

Thanks & Regards

Hi,

    We are porting our application from Tru64 Unix to HPUX 11.23 (IA64).

It is 64 bit application and multi-threaded. During runtime i have seen strange behaviour of our application.

 

I am using g++ of version 4.0.2.

 

when i run my application it is dumping core at

 

dmn_arr<desc_obj> tobj; #line no 200

 

where dmn_arr is a template class and it is crashing as

 

Program received signal SIGSEGV, Segmentation fault
  si_code: 1 - SEGV_MAPERR - Address not mapped to object.
0x9fffffffef7bce30:1 in dld_bor_text_entry + 0x81 ()
   from /usr/lib/hpux64/dld.so

 

As per my understanding the error SEGV_MAPERR is  it is not able to locate the template class od ( dmn_arr ).

 

Using gdb when i run the same application stepping each statement one by one it is working fine. if i put breakpoint directly at this statement( line 200) menetioned above  again it is dumping core as above.

 

What could be the problem. why i am getting this error. Any help is highly appreciated.
