@Jean you appear to be seeing a different problem; probably bad RAM. This problem is specific to DSO executables (built PIE or loaded via separate ld.so).
@Riku right, 64bit will not show it. 32bit PAE will only not show it if you have NX hardware (i.e. the CS-limit protections are not enabled in this case and are not used on 64bit at all).
