Segmentation fault when using dynamic library and virtual methods with Gcc 2.95.2

[Jacques.Herry@infineon.com]

GCC Version:
	gcc version 2.95.2 19991024 (release)
	with	GNU assembler version 2.11.2 (sparc-sun-solaris2.5.1) using BFD version 2.11.2
		GNU ld 2.11.2

Platform:
	SunOS chablis 5.5.1 Generic_103640-36 sun4u sparc SUNW,Ultra-4

Bug description:
	When a library containing class definitions with virtual method(s) is linked dynamically to a main program, a call to a dynamic method causes a segmentation fault (and a core dump).
	Calling the virtual method in the main program (even in a never used function !!!!) or linking in static mode avoid this crash.

	When compiling and linking the programs as follow, the execution crashes (segmentation fault).
	When uncommenting the lines 113 and 114 of BugMain.cc and recompiling, the execution is correct.
	When linking statically, the execution is correct.
	When including content of SmsXxlExceptionsXCL.cc/hh and SmsXxlOverflowXCL.cc/hh in BugMain.cc, the exeution is correct.

Library make:
g++  -v -g -DSMS_DEBUG=1 -mcpu=v8 -Wall -pedantic    -fPIC -c -o solrs251/GCC2952/dbg/dyn/SmsXxlExceptionsXCL.o SmsXxlExceptionsXCL.cc -I . 
g++  -v -g -DSMS_DEBUG=1 -mcpu=v8 -Wall -pedantic    -fPIC -c -o solrs251/GCC2952/dbg/dyn/SmsXxlOverflowXCL.o SmsXxlOverflowXCL.cc -I . 
g++ -Wl,-E  -v      -shared -fPIC -o solrs251/GCC2952/dbg/libSmsXxl.so solrs251/GCC2952/dbg/dyn/SmsXxlExceptionsXCL.o  solrs251/GCC2952/dbg/dyn/SmsXxlOverflowXCL.o

Executable make:
g++  -v -g -DSMS_DEBUG=1 -mcpu=v8 -Wall -pedantic -c -o solrs251/GCC2952/dbg/BugMain.o BugMain.cc -I. 
g++ -fPIC -Wl,-E  -v   -o solrs251/GCC2952/dbg/BugMain.exe solrs251/GCC2952/dbg/BugMain.o  -L/var/vob/softdev/Foundation/private/suites/Xxl/UnitTests/BUG_GCC_2/./solrs251/GCC2952/dbg  -R/var/vob/softdev/Foundation/private/suites/Xxl/UnitTests/BUG_GCC_2/./solrs251/GCC2952/dbg -Wl,-Bdynamic -lSmsXxl 

Content of attached tar-file:
	SmsXxlExceptionsXCL.cc/hh :	base class
	SmsXxlOverflowXCL.cc/hh :	derived class
		These files are linked in shared mode

	BugMain.cc :			main program
	make.log :			make log file

Please let me know if you'd like more information.
