labug1.f failure in web.c


Hi Jan,

You'll be hearing from the regression tester about this soon, but you
should know that your new web.c optimisation pass causes at least

FAIL: g77.f-torture/execute/labug1.f compilation,  -O3
-fomit-frame-pointer FAIL: g77.f-torture/execute/labug1.f compilation,
-O3 -fomit-frame-pointer -funroll-loops FAIL:
g77.f-torture/execute/labug1.f compilation,  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions FAIL:
g77.f-torture/execute/labug1.f compilation,  -O3 -g 

on powerpc-darwin.  The symptom is a crash, with:

#0  web_main () at
 /Network/Servers/cauchy/homes/thorin/gkeating/co/egcs-mainline/gcc/gcc/web.c:172
172             link = link->next;

with 'link' NULL.
