FWIW, my "non-franken-libgcj" builds always crash while
trying to compile java/lang/Character.java - specifically,
while compiling the "of" method of the "UnicodeBlock"
nested class.
Depending on planetary alignments, the crash is either
in the CALL_EXPR that calls _Jv_InitClass or in the
CALL_EXPR that calls _Jv_ThrowBadArrayIndex. The Tree-
SSA operands processing code crashes with a SIGSEGV
on these statements.
Apart from the fact that I know next to nothing about
SSA operands, my debugging sessions are always futile
due to the fact that I only get around 1-2 hours at
any time for such sessions (due to various reasons).
If there's anyone out there with a better knowledge
of Tree-SSA and a willingness to help resolve this
issue, it would be greatly appreciated.
Thanks,
Ranjit.
