--- Comment #13 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> --- (In reply to John Paul Adrian Glaubitz from comment #12) > Building with -O1 fixes the problem for me. Now I need to compare the flags > for -O1 and -O2 and check which one breaks the build. It's -fcrossjumping which causes the crash. Passing -fno-crossjumping fixes the build.
