Thank you for the hint. I wasn't aware of this tool. Now the output looks
better:
#linux_kdump -f ktrace.out | tail
84180 skype RET gettimeofday 0
84180 skype CALL gettimeofday(0xbfbfd810,0)
84180 skype RET gettimeofday 0
84180 skype PSIG SIGSEGV caught handler=0x82db000 mask=0x0 code=0x0
84180 skype CALL linux_rt_sigprocmask(0x1,0xbfbfd3d8,0,0x8)
84180 skype RET linux_rt_sigprocmask 0
84180 skype CALL linux_tgkill(0x148d4,0x148d4,0x6)
84180 skype RET linux_tgkill 0
84180 skype PSIG SIGIOT SIG_DFL
84180 skype NAMI "skype.core"
Nonetheless I have no clue why it coredumps. Could someone help me interpret
this trace? If needed I can provide the full trace or the core dump.
The problem can't be gettimeofday() I guess?
Thanks in advance
Tobias
