The following code example crashes g77 (segmentation fault) when invoked with the option "-finit-local-zero": PROGRAM TEST COMPLEX CZERO(1) END Use this command to trigger the error: g77 -c -finit-local-zero test.f On some code, using -fno-automatic fixes the problem, but not on the example above.

Create a simple test file such as test.f: PROGRAM TEST COMPLEX CZERO(1) END 2. Compile it with g77 using -finit-local-zero 3. Observe the sermentation fault Actual Results: $ g77 -c -finit-local-zero test.f test.f: In program `test': test.f:3: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://bugs.gentoo.org/> for instructions. Expected Results: Uh, well, not crash for one thing ;-)
Keeping this open isn't doing us any good. Waiting on the upstream patch, so marking this as later.
