Bootstrap failure

[Mark Mitchell]

On i686-pc-linux-gnu, I'm seeing:

stage1/xgcc -Bstage1/ -B/usr/local/i686-pc-linux-gnu/bin/ -c  -DIN_GCC    -W -Wall -Wtraditional -O2 -g -O2  -W -Wall    -I. -I.. -I../../../gcc/f -I../../../gcc/f/.. -I../../../gcc/f/../config -I../../../gcc/f/../../include ../../../gcc/f/com.c
../../../gcc/f/com.c: In function `ffecom_constantunion':
../../../gcc/f/com.c:10973: warning: `long' switch expression not converted to `int' in ANSI C
xgcc: Internal compiler error: program cc1 got fatal signal 11

Here's the backtrace:

We're executing this line:

  if (uid >= basic_block_for_insn->num_elements)

and `basic_block_for_insn' is NULL.  Anyone know what's up?

Thanks,
