[Bug pending/25118] New: PPC/-O2 bug causes segfault, -O1 works fine


NOTE: Defaulting component because reported component no longer exists
When the following program is compiled with -O2 (I used
$ gcc -O2 -save-temps zcopy.c -o zcopy -lrtgcc
), it will segfault. Not so with -O1. I've tried to make the program
shorter, but that didn't work and no longer segfaulted. Sorry.
