Wow, this looks like a compiler bug. When disassembling I see: src/util.c:226 f1597: 58 popl %eax f1598: 85 ed testl %ebp,%ebp f159a: 7e 1c jle f15b8 <get_keystroke+0xe4> But, %ebp doesn't seem to be set before this point. Further, the 'msec' parameter should be %eax at the start of the fuction, but %eax is clobbered near the top of the function. What version of gcc are you using? I'm currently using FC10: $ gcc --version gcc (GCC) 4.3.2 20081105 (Red Hat 4.3.2-7) Copyright (C) 2008 Free Software Foundation, Inc. This is free software; see the source for copying conditions.
