Continuation of the last one, different bug, building libstdc++ ...
Look familiar to anyone? If not, I'll try to hunt down the cause.
The culprit is this line:
D.25530 = (unsigned int) D.25529;
For m32cm, "int" is 16 bits, "long" is 32 bits, and "void*" is 24
bits. A cast to unsigned int truncates a pointer.
