SIGSEGV error in OpenJDK

I'm getting this from java-gnome programs (using GTK and Pango directly, nothing to do with AWT or Swing) as well as underneath Eclipse (which has its own SWT binding of Pango, so ditto). So I'm not sure it's a openjdk bug. In fact, I'm seriously doubting it.

Not OpenJDK specific.
I am using Eclipse 3.5 with Sun JDK 1.6 on amd64 and getting the same error.

this is a local eclipse copy. please recheck with eclipse in ubuntu lucid

I have the same problem using eclipse from repo on karmic: either or crash as provided in this report, or this error message:
Pango:ERROR:/build/buildd/pango1.0-1.26.0/pango/pango-layout.c:3736:pango_layout_check_lines: assertion failed: (!layout->log_attrs)

I use jdk-sun so the problem does not come from java but libpango I think.

Hi

Yes, Karmic is known to be broken (see LP: #531376); however eclipse in
Lucid (3.5.2-2) should be fixed

~Niels

Are you sure this is a duplicate of #531376? Because it mentions that the problem is fixed in Eclipse 3.5.2 but the problem of this bug still occurs in 3.5.2. The stack trace is also different. And the referenced Eclipse bug report there mentions that the bug only occurs with assistive technologies turned on, but I have it set to off and the bug occurs.

I'm seeing this in Eclipse 3.5.2 (build ID 20100218-1602) on Lucid. In fact, it started occurring after I did an upgrade to Lucid.

I've attached an example JVM crash log. It happens when Content Assist is opened, some of the time (seems to be consistent based on what's being auto-completed, always succeeds or always crashes, but I don't see a pattern).

Downgrading libcairo2 from 1.8.8.10 to 1.8.8.2 fixed the problem, as per https://bugs.eclipse.org/bugs/show_bug.cgi?id=309718
