The culprit is -finline-functions: The gcc man page says -O3 adds only 3 additional options. My bootstrapping script tells me the bug is in -finline-functions. Base compiler = gcc-4.1.2 (itself built without error using -O2), target compiler also gcc-4.1.2, when using -finline-functions as bootflags, the bootstrapped xgcc fails with an ICE at exactly the same place as originally reported above. Should -finline-functions be excluded from the default -O3 options? (until mended. If it can't be trusted building the comopiler, can it be trusted for anything else?) keywords added: build (problem occurs during bootstrap) wrong-code (compiles and links xgcc, but then xgcc fails later) ice-on-valid-code (the xgcc above fails with ICE during the build) -- anirkko at insel dot ch changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |build, ice-on-valid-code, | |wrong-code http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31523
