C2: server VM crashes when compiling make_jvmpi_method_exit

I create this new bug to separate the C2 problem from 4428927.

The following JVMPI tests fail with Merlin server VM in -Xcomp mode
when compiling make_jvmpi_method_exit:

nsk/jvmpi/GetCallTrace/calltr001
nsk/jvmpi/DisableEvent/disablev001
nsk/jvmpi/EnableEvent/enablev006
nsk/jvmpi/GetMethodClass/getmethc001
nsk/jvmpi/GetThreadStatus/thrstat002
nsk/regression/b4328316

Using JDK1.4 build 57 + build 59 server VM, these tests fail with an assertion in -Xmixed mode on both Solaris Sparc and WinNT:
#
# HotSpot Virtual Machine Error, assertion failure
# Please report this error at
# http://java.sun.com/cgi-bin/bugreport.cgi
#
# assert(dead_locals_are_killed(), "garbage in debug info before safepoint")
#

Using JDK1.4 build 59, some tests (such as disablev001 and b4328316) pass with -server -Xmixed mode on Solaris Sparc!! I haven't tried them on Win32. They fail with -server -Xcomp mode but got a SIGSEQV:
