GDB has problems reading GCC's debugging info level -g3

["R. Diez via Gcc-help" <gcc-help@xxxxxxxxxxx>]

Hi all:

GDB has issues with debugging info level -g3, see here for more information:

https://sourceware.org/bugzilla/show_bug.cgi?id=27754

I am no expert, but I suspect GCC may be buggy in this respect.

There are problems with debug (non LTO) builds, but the most issues come with when building with LTO, like for example missing or weird C++ symbols.

Are there know problems in this area? Any GCC bug reports I could subscribe to?

Thanks in advance,
