[Sdcc-user] SIGSEGV

[George M. G. <gga...@co...>]

I have a PIC18 program that is being ported from Microchip c18 to sdcc. Very
low priority. Environment is Red Hat 9.0 with sdcc source date 20040615.

The following routine fails compilation with:

Processor: 18f8720
Caught signal 11: SIGSEGV

0  byte GetByte(byte index)
1  {
2      uint16
3          addr, compAddr;
4      byte
5          val, compVal;
6   
7      addr = ConfigTbl[index].addr;
8      compAddr = ConfigTbl[index].addr + 1;
9
10    val = ReadLoc(addr);
11    compVal = ReadLoc(compAddr);
12
13    if ((val + compVal) != 0xFF) xxx();
14
15    return(val);
16 }
 

Moving line 8 to just before line 11 compiles correctly. Making the 
routine a standalone
file also compiles without error.  Moving it back allows 1 compilation 
without error, then
errors. Perhaps an uninitialized variable?
