Summary: Compilation Error - SIGABRT - SDCCopt.c

Initial Comment:
Dear developers,

The code attached along with this email is producing compilation error - SIGABRT 
Error details:
==========
Assertion failed: 0, file /home/sdcc-builder/build/sdcc-build/orig/sdcc/src/SDCCopt.c, line 707
abnormal program termination
Caught signal 22: SIGABRT

I tried the program with the following versions and the error is observed in both cases:

SDCC #5703
SDCC : mcs51/gbz80/z80/ds390/pic16/pic14/TININative/ds400/hc08 2.9.7 #5703 (Feb 21 2010) (MINGW32)

SDCC 2.9:
SDCC : mcs51/gbz80/z80/avr/ds390/pic16/pic14/TININative/xa51/ds400/hc08 2.9.0 #5416 (Mar 22 2009) (MINGW32)

Thanks for the great software. 

I am herewith attaching the test case and the batch file to build the testcase for your reference.

Thanks & Best Regards,
Raghu.

Message:
Something even simpler fails...

int * a;	
void main (void)
{
	int b;
	while(--b)
		*a = b * 3;
}

sdcc   loop-2c.c
/Users/sdcc-builder/build/sdcc-build/orig/sdcc/src/SDCCopt.c:707: failed
assertion `0'
Caught signal 6: SIGABRT

Same error with #5492 and #5710
