--- Comment #4 from Daniel Starke <daniel.f.starke at freenet dot de> --- I was able to build r222810 without bootstrap. However, the result remains the same. I am still getting the following error when linking all together: lto1.exe: internal compiler error: in add_symbol_to_partition_1, at lto/lto-partition.c:211 libbacktrace could not find executable to open Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. lto-wrapper.exe: fatal error: E:\msys\mingw64-64\bin\g++.exe returned 1 exit status compilation terminated. collect2.exe: fatal error: lto-wrapper returned 1 exit status compilation terminated.
