I had a macro (which converted a character into a hex value) which threw a
string exception when the character was not in one of the ranges I wanted.

Anyway, I receive the following ICE when I try to compile my code

bug.cc: In function `short unsigned int string2Hex (const char *)':
bug.cc:14: Internal compiler error.
bug.cc:14: Please submit a full bug report.
bug.cc:14: See <URL:http://www.gnu.org/software/gcc/bugs.html> for
bug.cc:14: instructions.

if the throw is replaced with a function call - no problem
(apart from inelegance)
if p_source[i] is replaced by a character literal - no problem

it's only when I have both the throw and p_source[i] in the same statement
that I get the ICE.

I didn't bother with bzip2 or uuencode b/c it's so small; hope this is ok.

BTW content of throwbug.s was

        .file   "throwbug.cc"
gcc2_compiled.:
        .global __throw
