It appears that and a similar fix for the ctype errors with the compaq
extended math library has resolved this issue.
Thanks again.
FYI.
I've found the following CFLAGS very useful on my Alpha:
CFLAGS=-O3 -mcpu=ev56 -mtune=ev56 -mieee -mno-soft-float -mfp-regs -pipe
-pthread
(the -mno-soft-float -mfp-regs attempt to use the internal FP components of
the Alpha processor and the -mieee corrects for NAN (not-a-number, e.g.
divide by zero) issues).
Anyone have other/better optimizations for ev56 class?

I appreciate the feedback. I haven't had the time myself to research and
thought I'd ask if anyone else had seen it. Before delving further into it
and filing a bug report. (I like to try and figure out the solution or at
least part way down the path before filing a bug).
I knew the runtime was the old compaq java and have been trying to locate a
source to a more recent release. Just some of the stuff I've installed on
my alpha now doesn't work as the jvm fails.
I'll try the patch when I get another shot at it and report back soonest.
