Here is some more diagnostic information. I simplified the code: 1. My original intent was to use my code in a sharelib, where __attribute__ (constructor) Initfunction() is also defined, for some initialization. Let us call the cpp fil with the __attribute__ statement as Test.cpp 2. to simplify , created a main.cpp with main() and compile it as binary ,it runs fine. 3. When i again link this main.cpp with the Test.cpp which has __attribute__ , then the code executes fine until an exception is throw in the code and inside the catch statement , i see a core dump and the see this error "terminate called after throwing an instance of '<Namespace>::<derived exception class from std::exepction>' terminate called recursively IOT/Abort trap (core dumped)" When I remove the Test.cpp file from compiler/linker, main.cpp works fine. When i put the file back, core dump happens. so inside the Initfunction() with __attribute__ (constructor) core dump is thrown, when I try to throw and catch an exception .
