I have just found that this bug can be triggered on/off using --param
large-function-insns=<something> option. Default value of this changed from
10000 before gcc-3_4-branch creation to 3000 shortly after.

All versions of 3.4.0 and 3.5.0 I tried (20040116..now) are OK with '-O1
-funit-at-a-time --param large-function-insns=10000' and all failed with '-O1
-funit-at-a-time --param large-function-insns=3000'.
