gzipped C++ source code
The attached C++ source code, with compiler flags -fno-strict-aliasing
and -O2, does this:
/home/dcb35/rpmbuild/BUILD/Vulkan-Tools-sdk-1.2.189.0/vulkaninfo/vulkaninfo.cpp:1082:1:
internal compiler error: in forced_merge, at ipa-modref-tree.h:352
The bug first occurs sometime before git hash 2fcfc03459a907c0,
from about a month ago.
I will try to reduce this source code downto somethine sensible.
