Per https://buildd.debian.org/build.php?pkg=r-base, we see the Alpha platform
having trouble with deriv.c :

gcc     -I. -I../../src/include -I../../src/include  -DHAVE_CONFIG_H  -mieee-with-inexact -fpic  -std=gnu99 -O3 -pipe  -g -c deriv.c -o deriv.o
deriv.c: In function 'simplify':
deriv.c:267: error: unrecognizable insn:
(insn 2103 64 65 9 ../../src/include/Rinlinedfuns.h:86 (set (reg:DI 2 $2)
        (const:DI (plus:DI (label_ref:DI 68)
                (const_int 24 [0x18])))) -1 (insn_list:REG_LABEL_OPERAND 68 (nil)))
deriv.c:267: internal compiler error: in extract_insn, at recog.c:2001
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.3/README.Bugs> for instructions.
make[4]: *** [deriv.o] Error 1

This could of course be a bug in gcc.  Does anybody have insights into
anything that may have changed here? 


Three out of two people have difficulties with fractions.
