[users@httpd] Exception handling - g++

["Chappidi, Sudhakar" <chappidi.sudhakar@xxxxxx>]

Hello All,

 

I am porting my application from Tru64 Unix to HPUX (Itanium). Now porting is complete and we are doing functionality testing. While doing functionality testing we have seen some strange runtime problems as described below.

 

I am using g++(gcc version 4.0.2 ) on HP-UX 11.11(Itanium). My application links with many shared libraries which are developed by us. All the shared libraries and executables are built with g++ ( 64bit build). I am seeing some times problems when there is exception handling.

 

When my application is running if there is any request which needs to processed.

 

1. Sometimes if there is any exception thrown,  it is not handled by the specific catch handler which is calling this function.
2. If that exception is caught by catch(…), It hangs in the catch block , ie it is not coming out of the catch block.

 

The same application works perfectly on windows and Tru64 Unix. We did not see this behavior on these platforms.

Any flags need to be set to the compiler explicitly for exception handling.

 

Can anyone help me in  this.

 

 

 

Thanks,

Sudhakar
