Comment 1 Mark Wielaard 2005-11-03 09:41:22 UTC
Confirmed, this prevents gjdoc from building, which used the build just fine with earlier gcj 4.0.x releases.
Comment 2 Andreas Tobler 2005-11-03 20:16:03 UTC
Todays gcc-svn HEAD compiles the jar fine. On ppc darwin.

Todays gcc-svn-gcc-4_0-branch fails with the below bt. Also on darwin.
