Hi,
What backend are you compiling with (java, c++)? Which x10rt
implementation are you linking with (sockets, standalone...)?
Do you have a small test case to share with us?
Could you try X10_STATIC_THREADS=1 instead just be sure this is not a
parsing issue?
Are you sure the setting is visible to the app (exported)?
Could you print Runtime.STATIC_THREADS at the beginning of your app?
BTW, X10_STATIC_THREADS is an undocumented feature.
It is not intended to support the full X10 language.
Many programs require this to be unset to run to completion.
