rsslEncodeFieldListComplete segfaults.

bneway

Hi. I am encoding a market price update message and rsslEncodeFieldListComplete receives SIGSEGV. Any ideas what the cause might be? As far as I can tell I am following the proper sequence of rsslEncodeFieldListInit, rsslEncodeFieldEntry, rsslEncodeFieldListComplete. In gdb, "disas" shows the following line where it segfaulted: "=> 0x0000000001245fcc <+92>: mov %dx,(%rax)". "x $rax" shows the following: "0x0: Cannot access memory at address 0x0". So clearly there is a NULL dereference. Any ideas what I might have done wrong? Thank you very much.

EDIT: I think I have identified the error and am looking into it. For the field entries I was using RSSL_DT_REAL but the values were RsslDoubles. I assume this is likely the cause

EDIT2: I have converted the values to reals. Now the RsslFieldEntry's dataType field is RSSL_DT_REAL and also the third argument to rsslEncodeFieldEntry is the address of a local RsslReal variable. It is still receiving segfault.

I needed the RsslFieldList flags to contain RSSL_FLF_HAS_STANDARD_DATA
