Summary: Unresolved symbols in libgcjgc.a when linking gctest
Product: gcc
Version: 4.5.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: boehm-gc
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: gcc-...@jupiterrise.com
Host: i386-pc-solaris2.9
On sparc-sun-solaris2.7 and i386-pc-solaris2.9 I'm seeing this when running the
testsuite.

ld: fatal: Symbol referencing errors. No output written to gctest

The reason seems to be that
http://gcc.gnu.org/ml/gcc-patches/2011-01/msg02288.html is missing on 4.5
branch.
Applying that fixes the issue for me.
