[Bug libgcj/37791] New: Regression in 0.98 merge tree

[Bug libgcj/37791] New: Regression in 0.98 merge tree

[gnu_andrew at member dot fsf dot org]

A few Mauve tests now throw an OutOfMemory error following the merge up to
Classpath 0.98:

TEST: java.lang.Character.Blocks15
  uncaught exception:
   java.lang.OutOfMemoryError
java.lang.OutOfMemoryError
   <<No stacktrace available>>


Strangely, the bug seems to be unreproducible outside the test harness (copying
all lines of code from Blocks15 to a new class and executing it cause the class
to run successfully).
