Thanks for testing.
I removed your test results (and the other stuff) from this message, not
because I'm not interested into, but because I have a new problem, which
prevents me to investigate further the original problem in the light of
your test results.
Since my last testings, I updated Cygwin, the JDK and the JRE. So, my
current configuration is now :
Windows Vista 32 bits SP2
When running the test case, I now have :
$ java jcmc
Loading library 'jcmc'...Exception in thread "main"
java.lang.UnsatisfiedLinkError: H:\cvs\epeios\bugs\jcmc\jcmc.dll: L'accÃs

There is a French message which roughly means "The access to this memory
location is not valid"
I updated the test case to reflect your changes :
- 'Makefile' now generates the '.h' file,
- 'Makefile' does no more contain the '--stdcall-alias' linker flag,
- the '.cpp' contains now the `extern "C"' directive,
- the '.h' is removed from test case, since it's now generated by the
I have the new error message with this modified test case, but also with
the original one. I suspect that the French error message is issued by
Cygwin or by one of its sub-component, since the JVM never issued a
message which wasn't in English, but Cygwin did.
So, I have to postpone the study of the 'malloc()' related bug until I
manage to resolve this new issue ; I then come back to your test results.
But, meanwhile, if someone has an idea why I have this new error...
Here again the address where the test case can be found :
