I've found this bug while building gcc 4.1.0 (on GNU/Linux x86). In the
'rebuild with -fprofile-use' stage I get the following error:
stage1/xgcc -Bstage1/ -B/usr/i386-unknown-linux-gnu/bin/ -c -O2 -g
-fomit-frame-pointer -fprofile-use -freorder-blocks-and-partition -DIN_GCC -W
-Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic
-Wno-long-long -Wno-variadic-macros -Wold-style-definition
-Wmissing-format-attribute -DHAVE_CONFIG_H -I. -I. -I../../gcc -I../../gcc/.
-I../../gcc/../include -I../../gcc/../libcpp/include ../../gcc/attribs.c -o

/tmp/cc9Aywrx.s: Assembler messages:
/tmp/cc9Aywrx.s:1256: Error: can't resolve `.text.unlikely' {.text.unlikely
section} - `.LCFI70' {.text section}
the line 1256 in the generated assembler output reads:
.long .LCFI71-.LCFI70
but the symbol .LCFI71 is in the .text.unlikely section while .LCFI70 is in
.text.
