Bug ID: 100446
Summary: GDB has problems reading GCC's debugging info level
-g3
Product: gcc
Version: 10.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: rdiezmail-gcc at yahoo dot de
Target Milestone: ---
GDB has excessive CPU load and memory usage with -g3 debug info. Sometimes it
makes GDB unusable.
There are problems with debug (non LTO) builds, but most issues come with when
building with LTO, like for example missing or weird C++ symbols. The release
ELF seems to have lost most C++ symbols, and there are many entries like this:
00010d6b l .debug_info 00000000
00010d6b l .debug_info 00000000
00010d6b l .debug_info 00000000
00010d6b l .debug_info 00000000

It looks like a GCC issue, and not a GDB issue.
I asked in the mailing list but got no answer at all:
