BZ #61: pango failure on ARM

Status fields:

version:default branch

op_sys:Linux
bug_status:RESOLVED
resolution:FIXED
reporter:huembi@objectxp.com 
I installed all packages from debian sid. Cacao is the only one I compiled myself
because the available packages (0.98) does not support the ARM-11 processor.


The Error

What other JREs did you test?  And do they use the same GNU Classpath installation?

Comment #6 by huembi@objectxp.com on 2008-04-08 14:35:47

I'm usign also jamvm 1.5.1
jamvm and cacao is working with classpath 0.97-1

Comment #7 by twisti@complang.tuwien.ac.at on 2008-04-08 16:30:17

The backtrace was a bit too early.  There is a SIGPWR, which is a signal thrown by
Boehm.  You need to disable the Boehm signals too:

(gdb) ha SIGPWR SIGXCPU nopr

Comment #8 by twisti@complang.tuwien.ac.at on 2008-04-08 16:30:55

And JamVM does not throw an InternalError?

This was a problem with floating point instructions.  Enabling soft-float fixed the
problem.
