It's a usual personal computer, where I expect glibc to find all the proper options automatically, and not cross compiling. Maintaining the proper alignment between calls depends on gcc, not glibc. A= nd I imagine glibc calls also maintain the alignment. I am pointing at the alignment at the dynamic loader; I imagine the dynamic loader runs that strstr() call without having passed the stage of aligning = the stack. Maybe in the initial report I forgot to say that looking at $ebp for every frame of the backtrace reported a misaligned %ebp, since _dl_start_user. --=20 Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=3Demail ------- You are receiving this mail because: ------- You are on the CC list for the bug.
