Hi! I came across the same bug in Ubuntu gutsy.
The problem is that the instrumentation function __mcount_internal uses the thread control block (the "cmpl $0x0,%gs:0xc"), but %gs is not initialized at this point, yet (mcount is called at the very start of __libc_start_main). As a crude work-around I replaced the "cmpl $0x0,%gs:0xc" and the following "je" with NOPs in libc_p.a which makes things work for me. best regards -Edwin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
