assertion failed on start in unusual environment

[x05elmja]

Omc fails to start if the following java code is used to start it:

Runtime.getRuntime().

exec(new String[] {"c:
OpenModelica13
omc.exe",

"+d=interactiveCorba"},

new String[] {"MODELICAPATH=c:
OpenModelica13"

+ "
ModelicaLibrary"});

The above code runs the command

'C:\OpenModelica13\omc.exe +d=interactiveCorba'

in an environment where the MODELICAPATH variable is set
to 'c:\OpenModelica13\ModelicaLibrary'.

However if you use the VC++ build of OMC version 1.3 (from the homepage) it
fails with the error message:

'This application has requested the Runtime to terminate it in a unusual

way...'

See the attached screenshot.

It also prints an error message to the stdout:

transport\tcp.cc:218: assertion failed

To run the program, unzip the archive it and type:

java OmcCrash

The program assumes that omc.exe is located in C:\OpenModelica13\

The following assert is triggered in mico source

MICO::TCPTransportServer::TCPTransportServer ()
{

OSNet::sock_init();

fd = ::socket (PF_INET, SOCK_STREAM, 0);
assert (fd >= 0);

....

Most probable cause: Security settings does not allow to open sockets???

owered severity to minor since most users wont trigger this bug. /PA.

the environment of the call was wrong,
the MODELICAHOME variable has to be appended to the existing environment.
I think this bug was fixed since a lot of time now.
