------- Comment #51 from redfive at songbirdnest dot com  2007-01-19 03:25 -------
I believe I'm seeing this bug using a redhat build: gcc4.1.1-1 (shows up all
the way through -51). It's only on 64bit FC5, 32bit is okay and am installing
FC6 to test. Building XULRunner with --enable-canvas causes the problem,
greater description of what I'm seeing is in their bugzilla:
https://bugzilla.mozilla.org/show_bug.cgi?id=367208

Basically a hidden symbol from .o to .a to linking in a .so gives the error
listed by the reporter here.

I can't tell from the comments which build will carry this patch. It looks like
it would be in 4.1, but the last comment re: backporting makes me wonder. Also
I wonder if this patch would have been pulled in to the Redhat build; I'm not
familiar with the relationship to the main gcc tree.

Thanks!
