gdb/1091: Constructor breakpoints ignored
|
|
gdb/1193: g++ 3.3 creates multiple constructors: gdb 5.3 can't set breakpoints
|
|
|
|
When gcc 3.x compiles a C++ constructor or C++ destructor, it generates
|
|
2 or 3 different versions of the object code. These versions have
|
|
unique mangled names (they have to, in order for linking to work), but
|
|
they have identical source code names, which leads to a great deal of
|
|
confusion. Specifically, if you set a breakpoint in a constructor or a
|
|
destructor, gdb will put a breakpoint in one of the versions, but your
|
|
program may execute the other version. This makes it impossible to set
|
|
breakpoints reliably in constructors or destructors.
|
|
|
|
gcc 3.x generates these multiple object code functions in order to
|
|
implement virtual base classes. gcc 2.x generated just one object code
|
|
function with a hidden parameter, but gcc 3.x conforms to a multi-vendor
|
|
ABI for C++ which requires multiple object code functions.

gdb/1322: "internal-error: sect_index_text not initialized" after printing a java type
|
|
|
|
When gdb debugs a Java program which uses shared libraries, it can
|
|
generate this internal error.
|
|
|
|
If you get this error when debugging Java, you can try working around
|
|
the problem by relinking your program with no shared libraries at all
|
|
(even the standard C library). With the GNU linker, use the "-static"
|
|
argument to do this.
