Precompiled source that causes this bug.
this works with gcc-4.1.2 and newer ... it's merely a segfault in the warning output, so it isnt like it cant compile valid code |
I have a somewhat complicated inheritance tree, and this is causing a segfault when compiling it with gcc. See attachment for my precompiled source. Reproducible: Always Steps to Reproduce: gcc -c -I ../shared/include -I ../shared/util -I ../drums -I ../shared/util/_val -I ../shared/util/_val/.. -D_CPP=1 -o objs/util_script.o ../shared/util/util_script.cc -v (I know the filenames mean nothing to you, but thought it best to leave my command line unaltered.)
