When running the VM tests with java_g and -Xdebug flag the test jit/common/t099
fails.
This doesn't fail if the -Xdebug flag is not used.
This also fails with 1.4.2 fcs so it's not a regression

Saw the error on Solaris 9x86 and Solaris 8 sparc.

The output from the tlog file is:

To reproduce compile the attached t099.java file
To run:

java_g -Xdebug t099

Expected output:
java.lang.StackOverflowError detected, thrown, and caught.

Actual output:
See hotspot error above.

======================================

This failure and others also seen on sparc 2.8 with 1.4.2_05

jit/common/gen_math/Loops_7 execute_positive Loops_7
jit/common/gen_math/Matrix_3d execute_positive Matrix_3d
jit/common/t099 execute_positive t099

again, omitting the -Xdebug flag lets them pass
Same results seen in earlier releases also.
attached is a tar file of test failures/info (vmfail.tar.Z)
