egcs-19990824: g++ -g -O generating bad assembly on x86 linux glibc-2.1.1

[Adam J. Richter]

	The latest snapshot (egcs-19990824) no longer generates an
internal compiler error in the example that I submitted previously.
In fact, it compiles that example without complaint.  However, it
still fails to compile the file from which I made that example.
Now it causes gas-2.95 (using bfd 2.9.5.0.8) to complain with the
following error messages:
/tmp/ccKnAoYo.s: Assembler messages:
/tmp/ccKnAoYo.s:166: Error: Subtraction of two symbols in different sections ".LBB5" {*UND* section} - "updateDrawingObjects__7QWidget" {.text section} at file address 644.
/tmp/ccKnAoYo.s:167: Error: Subtraction of two symbols in different sections ".LBE5" {*UND* section} - "updateDrawingObjects__7QWidget" {.text section} at file address 656.

	I have attached the smallest example that I could create of
code that generates the error.  Note that this error only occurs if
g++ is run with *both* -O and -g.
