[Bug c/37014] New: internal compiler error: in expand_expr_real_1, at expr.c:8760

trying to compile ath9k for mips or mipsel under openwrt toolchain with
gcc-4.2.4 produces the following error:

Please submit a full bug report,
with preprocessed source if appropriate.

a snapshot of the ath9k used is here:

a relative ticket on the ath9k is here:

gcc-3.4.6 compiles fine for mips & mipsel targets. gcc-4.2.4 also compiles fine
for x86 target.
