Segmentation Fault

rajanandhini — Mon, 28 May 2007 01:09:13 GMT

Hi,

We are in the process of migrating our old HP-UX 11.00, PA-RISC
architecture to a new HP-UX 11.23i, Itanium architecture. We have
compiled the codes and now we are testing the executables. While
running the executable, we get the following error.

SEGV_ACCERR - Invalid Permissions for object
#0 0x60000000c0340160:1 in _wrtchk+0x341 () from /usr/lib/hpux32/
libc.so.1

I am not sure why we are getting this error. Am pretty new to C and it
would great if someone can help me in this.

Thanks,

You need to provide a complete stack trace. You use gdb's "bt" command.

I'm guessing you are trying to use fwrite(3)?

Thanks for your suggestion. We used bt and below is its result. Sorry that i forgot to add it before.

Please let me know if anything more is needed.

Unless you have a bad FILE* value, you should look at the parms to fprintf and make sure they match with the format.

If you have a fairly new C compiler, A.06.05 or later (the latest is A.06.14), the compiler will warn if there is a mismatch.
