Right, debugging gccxml_cc1plus instead of gccxml let me hit the
breakpoint, but I didn't get very far after that. I'm not very
familiar with the innards of gcc, so debugging it is not easy.
But given that g++ 4.2 doesn't have any issues with that code, I
thought maybe I could look through recent gcc patches to find the fix.
I looked through a number of patches and also through the gcc sources
a fair bit, but so far, no luck.
I found the problem. It is in fact a bug in GCC 4.2's mangle.c but it
is exposed only by GCC-XML's call to it. Somehow mangle.c reaches a
case where it assumes that an enumeration value will be a simple integer
expression when in your example it is a less-than-comparison expression.
I've committed a hack to work around the issue:
/cvsroot/GCC_XML/gccxml/GCC/gcc/cp/mangle.c,v <-- mangle.c
