[Bug java/43086] New: PR16923 fails with Assertion failed: (class_id)

[howarth at nitro dot med dot uc dot edu]

On x86_64-apple-darwin9/10, the PR16923 libjava testcase, when linked to the
proper libiconv, fails with...

Assertion failed: (class_id), function main, file
/sw/src/fink.build/gcc44-4.4.2-1000/gcc-4.4.2/libjava/testsuite/libjava.jni/invocation/PR16923.c,
line 35.
Abort

A build of gcc-4.4.2 with the libgcc built with -O0 shows a backtrace of this
failure as...

#0  _Jv_AllocPtrFreeObj [inlined] () at java-gc.h:55
#1  _Jv_AllocString (len=Cannot access memory at address 0xf

When I run it by hand, I get:

$ DYLD_LIBRARY_PATH=../.libs:../../libgcc:/opt/local/lib ./PR16923
optionReceived

on x86_64-apple-darwin10 so this would be just a simple matter of ensuring the
setting of DYLD_LIBRARY_PATH, CLASSPATH and compiling with -L/opt/local/lib.  I
suspect DYLD_LIBRARY_PATH and CLASSPATH  are already correct.  I'm hoping you
can confirm this incantation works for you.

I've filed PR43839 that covers getting -L added, which I hope resolves this
issue.

------- Comment #3 from mrs at gcc dot gnu dot org  2010-04-21 19:02 -------
I've been able to confirm that with the hack patch in PR43839, this testcase
works on x86_64-apple-darwin10.

*** This bug has been marked as a duplicate of 43839 ***

Mike,
    The suggestion in Comment 2 works fine with my gcc trunk build on
x86_64-apple-darwin10 (assuming one fixes the-liconv linkage manually)...
