            Bug ID: 82263
           Summary: java multilib -m32 version is using 64 bit include and
                    lib, _GStaticAssertCompileTimeAssertion_0
           Product: gcc
           Version: 6.4.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: java
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gccbugzilla.severach at spamgourmet dot com
  Target Milestone: ---

Snapshot 6-20170913 fixed all glibc 2.26 issues except for the -m32 multilib
version of the java compiler. It halts with

/usr/include/glib-2.0/glib/gmacros.h:232:53: error: size of array
‘_GStaticAssertCompileTimeAssertion_0’ is negative

This is because it is including a 64 bit
/usr/lib/glib-2.0/include/glibconfig.h. I can patch the makefile to get it to
use the 32 bit /usr/lib32/glib-2.0/include/glibconfig.h which completes the
compile then crashes on linking to the 64 bit libs.

$ pacman -Q gcc-multilib glibc
gcc-multilib 7.2.0-1
glibc 2.26-4

$ gcc -v
