I'm still hitting this failure when building GMP 5.1.0 for i686-w64-mingw32:
libtool: compile: i686-w64-mingw32-gcc -std=gnu99 -DHAVE_CONFIG_H -I.
-I../../../../src/gmp/mpn -I.. -D__GMP_WITHIN_GMP -I../../../../src/gmp
-DOPERATION_sbpi1_div_qr -O2 -march=nocona -mtune=core2 -fomit-frame-pointer
-momit-leaf-frame-pointer -c sbpi1_div_qr.c -o sbpi1_div_qr.o
div_qr_2u_pi1.c: In function '__gmpn_div_qr_2u_pi1':
div_qr_2u_pi1.c:67:1: internal compiler error: Maximum number of LRA constraint
passes is achieved (30)
}
^
Please submit a full bug report,
with preprocessed source if appropriate.
The build for x86_64-w64-mingw32 did not encounter this problem. I'm building
on 64-bit Debian using a self-built linux to Windows cross-compilers.

I can also add that GMP 5.0.5 does not trigger this ICE.

Could you provide a preprocessed source code. I'd try to reproduce this. In
any case, it will be not fixed quickly. I am on vacation next two weeks.
Sorry.
