Initial Comment:
Command line to compile: C:\sdcc\bugs\sips>..\..\bin\sdcc sips.c -mz80 -c --codeseg CODE5
I am testing snapshot build 6069 downloaded directly
C:\sdcc\bugs\sips>..\..\bin\sdcc -v
SDCC : mcs51/gbz80/z80/ds390/pic16/pic14/TININative/ds400/hc08 3.0.1 #6069 (Nov 29 2010) (MINGW32)

This problem is complicated so I attached the whole sips.c and all include files needed.
In sips.c line 2078 to 2082
if (Sip_pCurLcb->pReqUri) free(Sip_pCurLcb->pReqUri);
Sip_pCurLcb->pReqUri = heap_save_str(pBuf);
if (Sip_pCurLcb->pInvUri) free(Sip_pCurLcb->pInvUri);
Sip_pCurLcb->pInvUri = heap_save_str(pBuf);
both Sip_pCurLcb->pInvUri and Sip_pCurLcb->pReqUri will be incorrectly set to 0 in real run.
However, if rearrange them to:
if (Sip_pCurLcb->pReqUri) free(Sip_pCurLcb->pReqUri);
if (Sip_pCurLcb->pInvUri) free(Sip_pCurLcb->pInvUri);
Sip_pCurLcb->pReqUri = heap_save_str(pBuf);
Sip_pCurLcb->pInvUri = heap_save_str(pBuf);
We can get correct none-zero pointers.

I am attaching sips_2.zip which used in 6069 test.
