Hi,

I'm using the JDK pre-beta 1, static motif version, with ld.so.1.7.11
(from ftp.ods.com), libc.5.0.9, libgmalloc on a Slackware 3.0 ELF system 
with kernel version 1.2.13.

I've checked the following things:
- link bin/i486 to bin/i586, and lib/i486 to lib/i586
- permissions on /dev/zero and /dev/null are ok
- using 8 bpp display
- use /bin/sh, remove 'whence' and fix paths in .java_wrapper

But it still segfaults. Here's what happens (I added echos for 
the environment variables):

/usr/local/pkg/jdk.pre1.static-motif/bin# javac MyAwtApp.java
JAVA_HOME=/usr/local/pkg/jdk.pre1.static-motif
CLASSPATH=.:/usr/local/pkg/jdk.pre1.static-motif/classes:/usr/local/pkg/jdk.pre
1.static-motif/classes.zip
LD_LIBRARY_PATH=/lib:/usr/X11/lib:/usr/local/pkg/jdk.pre1.static-motif/lib/i486
prog=/usr/local/pkg/jdk.pre1.static-motif/bin/i486/javac
opts=

SIGSEGV   11*  Segmentation violation

Full thread dump:

and then it hangs, busy-looping (it never actually prints a thread dump).
Ctrl-C gets back to a prompt. All the other programs called by 
.java_wrapper do the same thing.

So, what did I miss?
