--- Comment #29 from Angelos Oikonomopoulos <angelos at igalia.com> ---
So, to summarize:

- clang + gdb is currently a no-go. I don't see a workaround for this ATM, so this would need to be fixed upstream in GDB. Have opened an issue on their bugzilla. In any case, it'll be quite some time before the fix is available in the toolchains that people use.
- gcc + gdb should work with this patch.

The only downside I can see so far is the extra #if COMPILER(GCC) directives for the MARKER_SYMBOL. I could remove those by making MARKER_SYMBOL a no-op on !GCC. My preference is for the former, as it's more explicit, but can easily submit the latter approach too.

Would be great to have this upstream, so looking forward to fixing any remaining issues.
