[erlang-questions] FW: SMP VM DUMPING CORE

[Rickard Green]

The 64-bit compiled smp emulator on sparc erroneously used the 32-bit 
implementation of atomic variables which caused it to crash. We didn't 
notice this since we currently aren't running any automated tests on 
64-bit sparc.

Unfortunately a fix for this issue will not make it into the R12B 
release. I will however post a source patch for R12B fixing this issue 
later.

BR,
Rickard Green, Erlang/OTP, Ericsson AB.
