I used gdb and traced the bug to a call instruction. I dissasembled the code and stepped through the instructions. The program got a segmentation fault when it executed an assembly language call instruction. Using gdb I was able to disassemble the instructions at the called address. Why can gdb disasemble instructions at a call address and a call to that address fails with a segmentation fault? Is this a kernel problem? I am using kernel version 2.2.15. Any suggestions would be appreciated. I tried kernel 2.4.4 and the same thing happens. I have searched this mailing list archive and did find some posts about segmentation faults/ kernel bugs, but they did not resolve this problem. I use egcs 1.1-2 and ld 2.9.5 versions. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ -- _________________________________________________________________________ Terje Eggestad terje.eggestad@scali.no Scali Scalable Linux Systems http://www.scali.com Olaf Helsets Vei 6 tel: +47 22 62 89 61 (OFFICE) P.O.Box 70 Bogerud +47 975 31 574 (MOBILE) N-0621 Oslo fax: +47 22 62 89 51 NORWAY _________________________________________________________________________
