GCC is doing the correct thing. Glibc is broken so closing as invalid as glibc
has already been fixed.

In that case the bug report is incorrect.
The problem lays in glibc, in function lroundl which does not save cr3.

So maybe someone is violating the PPC ABI.

CR3 is a caller save register just like R31.

IIRC cr3 is a volatile conditional register.

I was trying to isolate the code which triggers this bug, but seems like the
code must be very complex to do so. Nevertheless I found exactly how the
resulting assembler code is broken.
Note: files gsignal.s and gsignal
