[Bug debug/41342] New: Var tracking appears to run out of memory .


For the attached case distilled from eglibc sources - the compiler ends up by
running out of Virtual memory for compilations with -O2 -g . Turning this off
using -fno-var-tracking-location appears to workaround the issue.

Here's the memory usage that I see for this one.  


 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND 
32172 ramana    20   0 3047m 2.7g 3856 R   67 92.4   0:57.00 cc1 


The tools were configured with --target=arm-none-eabi --with-float=softfp
--with-fpu=neon . However running the attached testcase with march=armv4t
mfpu=vfp and mfloat-abi=soft doesn't have any different visible effects.
