signal 11 issue using JNI

hi all,

i've been working on a problem for days now and not making any
progress, i'm hoping someone out there can help:

i am using JNI to access a C++ API (it's well tested and stable).
when i build the native modeule (the .so) on redhat 8.0 with gcc 3.2
and run it on the blackdown JVM (compiled with gcc 3.2) everything
works fine.

however, i have a requirement that the application must run on redhat
7.2. so i installed rh7.2 and tried to run my app. it wouldn't run
because the c/c++ runtime libraries are of an older version on 7.2 and
the ABI for gcc2.96 and gcc3.2 is different. so i recompiled the
native module with 2.96 and got a signal 11 outside the VM. so i
upgraded gcc and the standard c++ libraries to version 3.0.4 (the
latest available for rh72) and tried again. same error (see below).
this is also the error i get when i try to run this app with the sun
jvm (btw, all JVMs i use are 1.4.1).

i'm guessing this is some sort of compiler/library incompatibility
issue, but my linux/c++ skills are rusty and i don't know how to go
about resolving this. the strange thing is that the calls to the
native c++ file that i wrote (cpp file corresponding to the h file
generated by javah) succeed and return if i make no calls to the C++
API i'm trying to integrate with, but as soon as a call into that API
is made, signal 11. it might also be relevant to mention that i'm
accessing the C++ API by compiling and linking it's source statically
directly with my cpp files, so it's not an issue with how the C++ API
is linked.

any help or insight would be greatly appreciated. please email me
directly (roncarmel AT yahoo DOT com) as i don't often read
newsgroups.

here is the error:

An unexpected exception has been detected in native code outside the
VM.
Unexpected Signal : 11 occurred at PC=0xBFFFCB75
Function=[Unknown.]
Library=(N/A)

NOTE: We are unable to locate the function name symbol for the error
just occurred. Please refer to release documentation for
possible
reason and solutions.

It's hard to say. I would suggest running the failing app in
gdb and trying to trace it that way. Build it will full
symbols first, of course.

If this an SMP box, make darn sure you are using a 2.4.18 or
later kernel, prior to that kernel level there are nasty
bugs regards Java on SMP boxes. I'd take a gander at the
release notes for your JVM version and see if it has any
special notes on Linux JNI issues (required library levels,
etc.)

If you don't find anything, I'd start with a simple test
library with a dummy native method and test that out to see
if it works ok.
