internal error in 3.3.3 building arm cross-compiler

[Dave Denholm]

I was trying to install gcc 3.3.3 as a crosscompiler on solaris/x86 compiling
for arm-elf using "newlib"


I got an internal error when compiling some (thumb ?) code.
Since it's running the locally-built compiler, I assume it's trying to
compile some library code ?

The cross-compiler itself would be have been built using a native
(solaris/x86) gcc 2.95.2

eclipse:~/tmp$ gcc -dumpmachine
i386-pc-solaris2.8
eclipse:~/tmp$ gcc --version
2.95.2



dp-bit.c: In function `__pack_d':
dp-bit.c:411: error: insn does not satisfy its constraints:

I hope there's enough information in the following to figure out the
problem (or recognise this as a duplicate report)
