Description Blu3 2005-03-13 15:13:31 UTC

Someone has included a patch for gcc for the visibility pragma, however they need to add an additional patch.  Without it, gcc can burp with unpaired push/pops for visibility.

This affects the building of Mozilla, it results in the failure to link, misdiagnosed as a linker issue but it's actually a gcc bug.

Please include the patch listed at this URL in an update for gcc.

Thank you.
