27: Bug Report for GCC:
28: -------------------
29: Problem : Gcc 1.24 generates code that overwrites a register used in a
30: subsequent instruction. (this was a *hard* bug to track down!!). This
31: error results in a core dump when the program is executed. Compiling
32: *without* -O results in a working program.
