#1348 Array initialization makes compiler crash.

[Philipp Klaus Krause]

Compiling the attached source containing two loops the compiler crashes.

I compile using
sdcc -c -mz80 --srd-c99

Compiler version:
2.7.2 #4861

It seems it's not the loops, but the array initialization in the outer loops that makes sdcc crash.

I'm not sure this is a Z80 problem even though I see it only when targeting Z80 port.
Here's a gdb backtrace, using #5027:

This seems to be the same bug as 1888147. It is now fixed in SDCC 2.7.5 #5029.
