Error description

  • When compiler a large test case, the compiler front end runs out
of memory and produces a "Insufficient memory at compile time"

workaround.

Problem summary

The problem was exposed in generated code which had a
combination of many local
variables requiring ctor/dtor calls and many different return
statements.

PROBLEM DESCRIPTION:
Each return statement was duplicating the dtor calls for the
local variables,
there by causing the compiler was running out of memory due to
the large number of duplicates.
