Okay. Now I found something: inst/bin/powerpc-linux-gnuspe-gcc extract_chmLib.i -o extract_chmLib.S -S -O2 extract_chmLib.c: In function '_extract_callback': extract_chmLib.c:29: internal compiler error: in change_address_1, at emit-rtl.c:1954 Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. extract_chmLib.i is attached. Adding -mfloat-gprs=single which avoids using 64bit gprs for double makes this go away. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44364
