Parallel assignment of map entries crashes compiler

[gopherbot]

by punya.biswal:

What steps will reproduce the problem?
1. Assign two entries of a map in the same expression, like so:
   x := make(map[int]int, 10);
   x[0], x[1] = 2, 7

What is the expected output? What do you see instead?
Both entries should be assigned. Instead, the compiler (6g) segfaults.

What is your $GOOS?  $GOARCH?
GOOS=linux
GOARCH=amd64

Please provide any additional information below.
Parallel assignment works just fine for arrays.
