I just tried to compile the package luminance-hdr-2.3.0-6
on gcc-4.9 trunk dated 20130428 on an AMD x86_64 box.

The compiler said

/home/dcb/rpmbuild/BUILD/luminance-hdr-2.3.0/src/Fileformat/pngwriter.cpp:205:1:
internal compiler error: tree check: expected ssa_name, have var_decl in
unlink_stmt_vdef, at tree-ssa-operands.c:1322
 }
