Exception "terminate called after throwing an instance of 'std::bad_typeid'"

Exception "terminate called after throwing an instance of 'std::bad_typeid'"

Hi,

Linux 2.6.18-238.1.1.el5 #1 SMP Tue Jan 4 13:32:19 EST 2011 x86_64 x86_64 x86_64 GNU/Linux

Intel C++ Intel 64 Compiler XE for applications running on Intel 64, Version 12.0.0.084 Build 20101006

We have got exception "terminate called after throwing an instance of 'std::bad_typeid'" in the following situation.

This test has been created by Sela Lerer, I have added SHOW_PTR and SHOW_TYPEID.

Any suggestions?

Thanks

One more thing.

If RTLD_GLOBAL is used instead of RTLD_LOCAL (in main.cpp) then no exception occurs.

Alex

You need toprovidelibdyn.so during link. I modified the make file as givebelow. IT works.

$ cat Makefile

test: libdef.so libdyn.so main.cpp

icpc -c main.cpp

icpc -o test main.o -L. -ldyn

libdef.so: libdef.cpp

icpc -o libdef.so libdef.cpp -shared -fPIC

libdyn.so: libdyn.cpp libdef.so

icpc -o libdyn.so libdyn.cpp -shared -fPIC -L. -ldef

clean:

rm test main.o libdef.so libdyn.so

$ ./test

libdyn.cpp: pBase = 0x2581180

libdyn.cpp: typeid(Base) = 4Base

libdyn.cpp: typeid(Base*) = P4Base

libdyn.cpp: typeid(pBase) = P4Base

libdyn.cpp: typeid(*pBase) = 7Derived

libdyn.cpp: typeid(Derived) = 7Derived

libdyn.cpp: typeid(Derived*) = P7Derived

libdyn.cpp: typeid(pDerived) = P7Derived

libdyn.cpp: typeid(*pDerived) = 7Derived

CAST SUCCEEDED

Om, thank you very much.

Alex

One more question.

Only icpc-linker requires L. -ldyn while linkage of executable files.

Other linkers produce valid typeid() without L. -ldyn while using RTLD_LOCAL.

Is there any option in icpc to guarantee such behavior (without L. -ldyn)?

Thanks,

Alex V.

I'm having an issue similar to this with the newer "icpc" compiler. uname -a Linux linux-xsic.site 3.4.33-2.24-desktop #1 SMP PREEMPT Tue Feb 26 03:34:33 UTC 2013 (5f00a32) x86_64 x86_64 x86_64 GNU/Linux icpc -V Intel(R) C++ Intel(R) 64 Compiler XE for applications running on Intel(R) 64, Version 13.1.0.146 Build 20130121 Copyright (C) 1985-2013 Intel Corporation.
