>Release: GDB-5.1
>Organization:
>Environment:
SuSE Linux 7.3 (Kernel 2.4.10)
>Description:
Under certain conditions GDB can't access elements of a class (e.g. "this->value"). Instead the error message "Cannot access memory at address ..." is generated, which makes GDB almost completely useless for such programs. This bug has been introduced with GDB-5.0, GDB-4.18 doesn't show this errorneous behaviour.
>How-To-Repeat:
1.) save the attached program as "test.cpp" and compile it with "g++ -g test.cpp -o test"
2.) start gdb as "gdb test" and step into the constructor cls3::cls3()
3.) type "print x" to demonstrate the bug
4.) step out of the constructor and type "print obj3" to see that the code has been compiled correctly
