and then
with __attribute__((optimize("no-tree-pta","no-ipa-modref")))
the code unit compiled without ICE.
The optimizations are in O1, however if i simply use
__attribute__((optimize(2))),then the code unit does compile too, which is
really weired.
There's similar(may be same?) issues in here:
https://github.com/msys2/MINGW-packages/issues/11726 , ICE in same gcc code
location (symtab.cc:2494), with different flags though.
