Bug 507230 – sys-devel/gcc-4.8.2-r1 - gdb pretty printers are incompatible w/ Python3

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Alex Turbov 2014-04-09 11:01:27 UTC]

"Starting with gdb-7.6, gdb supports embedding a Python3 interpreter instead of
Python2.  However most pretty printers are still using Python2 code..."

i think we'd rather wait for upstream gcc to land something and then we'll cherry pick that back

The closest upstream bug is http://gcc.gnu.org/PR58962.  I haven't seen any patches posted.

Fix committed upstream:

[Comment 5 SpanKY 2015-08-30 06:20:15 UTC]

should be fixed w/gcc-4.8.[45] and gcc-4.9.[23] and >=gcc-5

don't see much point in backporting past that
