The error only happens when optimizing is turned on. It doesn't happen with my native
compiler gcc-2.95. Since both gcc-2.95 and egcs-19991004 are compiled with
gcc-2.95, I think its a bug inside egcs-19991004.
xgcc (aka egcs-19991004 itself is a crosscompiler for i386 and i486 based
boards using an embedded RTOS called micros.)
