I've started running acceptance tests on MIPS. It takes a lot of time, but so far everything passes.
If this assert was happening frequently, there's one of two possibilities:
 1. It was fixed in the meantime
 2. It wasn't run with -Dinterp. Since this assert is in VMCFG_FLOAT code, I presume that the binary was built with float enabled. Since float/float4 is not yet supported on MIPS, it's only logical to encounter assertions, unless the code runs in interpreted mode exclusively.
