Subject: [Bug lto/45141] New: lto1 ICEs when linking cns_solve again
Date: Fri, 30 Jul 2010 10:42:00 -0000 [thread overview]

Current gcc trunk (but not gcc 4.5.1) ICEs when linking cns_solve using -O2
-fwhopr -fwholeprogram. The reduced test case is attached and crashes as...

lto-wrapper: gfortran returned 1 exit status
collect2: lto-wrapper returned 1 exit status
The lto1 ICE doesn't occur if the optimization is reduced to -O1 or if the
-fwhole-program flag is omitted.
This crash is distinct from the the resolved one from PR45037.
