From Bugzilla Helper: User-Agent: Mozilla/4.7 (Macintosh; I; PPC) Description of problem: Trivial program trying "call exit(%val(zero))" (admittedly a strange thing to try) generates gcc-g77 internal error. Like this: >cat tmp2.f program tmp c checks exit status flag connection implicit none integer *8 zero parameter (zero = 0) call exit(%val(zero)) end > g77 -c -fno-underscoring tmp2.f ../../../gcc/f/com.c:3863: failed assertion `"bad op" == NULL' tmp2.f: In program `tmp': tmp2.f:6: Internal error: Aborted. Version-Release number of selected component (if applicable): Name : gcc-g77 Relocations: (not relocateable) Version : 2.96 Vendor: Red Hat, Inc. Release : 85 Build Date: Wed 09 May 2001 11:04:50 AM PDT Install date: Wed 11 Jul 2001 10:08:28 PM PDT Build Host: porky.devel.redhat.com Group : Development/Languages Source RPM: gcc-2.96-85.src.rpm Size : 4071462 License: GPL Packager : Red Hat, Inc. <http://bugzilla.redhat.com/bugzilla> How reproducible: Always Steps to Reproduce: 1.g77 -c -fno-underscoring tmp2.f (see above for tmp2.f) 2. 3. Actual Results: g77 -c -fno-underscoring tmp2.f ../../../gcc/f/com.c:3863: failed assertion `"bad op" == NULL' tmp2.f: In program `tmp': tmp2.f:6: Internal error: Aborted. Please submit a full bug report. See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions. Expected Results: tmp2.o Additional info:
Actually, any g77 will fail this way. Not being a Fortran speaker, I passed this on to GCC Fortran maintainer.
Fixed for 3.2 tmp2.f: In program `tmp': tmp2.f:6: call exit(%val(zero)) ^ Too many arguments passed to intrinsic `EXIT' at (^)
