--- Comment #2 from Simon Marchi <simon.marchi at polymtl dot ca> ---
So, I don't see that specific failure with gdb/d-lang.c nowadays, but I see one
similar with gdb/symfile.c (see below). However, it seems fixed with gcc 15.
I just tested with these versions:
11.5.0: works
12.5.0: fails
13.4.0: fails
14.3.0: fails
15.2.0: works
I am able to build GDB with gcc 15, with "-O2 -fsanitize=address
-D_GLIBCXX_DEBUG=1", so I will close this bug.
---
For reference, the error I get with symfile.c:
$ ccache /opt/gcc/14.3.0/bin/g++ -x c++ -I.
