Has any progress been made on this bug? It still affects AIX 6.1 on gcc Version
4.7.2 compiling a 64 Bit gSOAP generated source.

AIX:doug:1> oslevel
6.1.0.0
AIX:doug:1> gcc -v
Using built-in specs.

Current ulimit values:

core file size  (blocks, -c) 1048575
data seg size   (kbytes, -d) 262144
file size   (blocks, -f) 2097151
max memory size (kbytes, -m) 32768
open files  (-n) 2000
pipe size(512 bytes, -p) 64
stack size  (kbytes, -s) 131072
cpu time   (seconds, -t) unlimited
max user processes  (-u) unlimited
virtual memory  (kbytes, -v) unlimited


I changed the ulimits below, but had the same results. Note that this source
compiles as 32 Bit on AIX 5.3 using 'gcc version 4.2.4'.

ulimit -d 393216
ulimit -m 65536
ulimit -s 262144
ulimit -n 4000

/tmp//ccZ4WBed.s: line 2939315: 1252-171 The displacement must be greater than
or equal to
-32768 and less than or equal to 32767.

When you say rebuild GCC cc1/cc1plus with even larger -bmaxdata, are you
refering to the AIX environmental 'export LDR_CNTRL=MAXDATA=0x5000'? Is
this the recommended value?
