# Tcl Bug 1001997
|
||
# Here, we're trying to test a case that causes a crash in
|
||
# TclCleanupLiteralTable. The conditions that we're trying to establish
|
||
# are:
|
||
# - TclCleanupLiteralTable is attempting to clean up a bytecode object in
|
||
# the literal table.
|
||
# - The bytecode object in question contains the only reference to another
|
||
# literal.
|
||
# - The literal in question is in the same hash bucket as the bytecode
|
||
# object, and immediately follows it in the chain.
|
||
# Since newly registered literals are added at the FRONT of the bucket
|
||
# chains, and since the bytecode object is registered before its literals,
|
||
# this is difficult to achieve. What we do is:
|
||
# (a) do a [namespace eval] of a string that's calculated to hash into
|
||
# the same bucket as a literal that it contains. In this case, the
|
||
# script and the variable 'bugbug' land in the same bucket.
|
||
# (b) do a [namespace eval] of a string that contains enough literals to
|
||
# force TclRegisterLiteral to rebuild the global literal table. The
|
||
# newly created hash buckets will contain the literals, IN REVERSE
|
||
# ORDER, thus putting the bytecode immediately ahead of 'bugbug' and
|
||
# 'bug4345bug'. The bytecode object will contain the only references
|
||
# to those two literals.
|
||
# (c) Delete the interpreter to invoke TclCleanupLiteralTable and tickle
|
||
# the bug.
