Subject: [PATCH] lower optimization for dispatch code when using C + tsb
|
|
|
|
there appears to be some bug in the code which causes crashes
|
|
with threaded opengl setups; this manifests at least on ppc64(le)
|
|
with musl (where one must set `-Dtls=enabled`). I haven't been
|
|
able to track it down yet, but this workaround at least makes it
|
|
stop happening.
