Also, ich habe ein bischen nachgeforscht in dem ich mir assembler code beim gcc generiren lassen habe.
Es sieht so aus, Fehlerquelle bold markiert.

Leider weiter meine Assembler Kenntnisse sind nicht ausreichend. Aber ich vermute es liegt and dem statement, nämlich "(void*)-1"
if (__builtin_expect (filedata == ((void *) -1), 0))
Oder an etwas in der Art.
Ich würde mich sehr freuen auf ein Workarond für das Problem oder ein Tip. Wenn jemand Lust und Ahnung hat ich kann die drei loadlocale Dateien per mail zu senden.
loadlocale.c // sources
loadlocale.i //preprocessed sources
loadlocale.s //assembler code
Danke in voraus
mal versucht das ganze auf meiner Workstation zu compilieren.
