Comment 1 Red Hat Bugzilla 2000-08-19 01:56:38 UTC 
array.c in mawk 1.3.3-4 is miscompiled by -O2. -O seems ok.
Comment 2 Red Hat Bugzilla 2000-08-19 17:43:33 UTC 
Using -O2 -fno-strength-reduce on array.c generates a working mawk.
BTW, gcc 2.96 20000819 still miscompiles mawk.
Comment 3 Red Hat Bugzilla 2000-08-20 00:15:21 UTC 
Jakub is fixing this problem in gcc. Thanks for your report.
Comment 4 Red Hat Bugzilla 2000-08-21 13:51:53 UTC 
a workaround was made in mawk as well.
