Bug 625696 – dev-util/codeblocks-16.01 segmentation fault with gcc-6

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Keith Harrison 2017-07-19 19:42:23 UTC]

Builds fine with gcc 6, but crashes immediately on startup.

After rebuilding world recently, this happens consistently on multiple computers.

Reading symbols from codeblocks...(no debugging symbols found)...done.

Quick workaround (but this may break other things):

package.env:
x11-libs/wxGTK gcc5.conf
dev-util/codeblocks gcc5.conf

gcc5.conf:
CC="gcc-5.4.0"
CXX="g++-5.4.0"
