I am still having trouble getting hellworld to run. Currently the problem
is that for some reason in dll_jit.cpp on line 62, where the call is made to
apr_dso_load, the second parameter which is the path to the dll becomes
address out of bounds in the apr_dso_load procedure.
Egor suggested that perhaps APR configured itself incorrectly on my system.
Alexey suggested I try to run the APR test. I ran the APR tests and all
tests passed (in /build/lnx_ia32_gcc_debug/semis/extra/apr/src/test).
Below is what happens in gdb. Also below that I have pasted what happens at
the end of the output when I run ./java -Xthread -Xtrace helloworld.
Another thing that is suspicious is that when I run ./java it works fine,
but if I run "./java -Xthread -Xtrace" it does not run fine (it hangs inside
GetObjectClass). I have also pasted the end of the trace for this.
Let me know if there is any other debugging information I can provide.
