- generic/nsfStack.c / CallStackPopAll(): When cleaning up the unstacked CSC entries, the borderline case of just 1 CSC entry led to a dangling pointer (and so a crash). This was caused by the unhandled side effect of CscListRemove() (or, rather, NsfClassListUnlink()) which updates the interp's cscList pointer in the 1-list-entry scenario. By using a copy of this pointer in the cleanup loop, this scoped pointer became dangling. To reproduce the issue (prior to this commit), run for example:

Object create o { exit -1 }

I extended the CscListRemove() interface for a conditional out

parameter, to be used for tracking changes to the interp's cscList

pointer.

- generic/nsf.c: Modified the occurrences of CscListRemove() to

reflect its extended interface.

- generic/nsfStack.c: Extended the documentation snippets of the

CscList* operations accordingly.

- generic/nsf.c / NextSearchAndInvoke(): Prior to this commit, next calls from within submethod leaves resulted in the interp's unknown flag to be set. While for dispatches without filter indirection this remains hidden and unnoticed, registered filters triggered an unwanted unknown dispatch in such scenarios. Consequently, such leaf next's in submethods behaved differently from the method equivalents. The patch identifies such leaf-next dispatches by watching out for a characteristic callstack structure. - tests/submethods.test: Add a characteristic test for the above patch. - tests/disposition.test: Some cleanup ...

- generic/nsf.c: Fixed [current callingmethod] for submethods (i.e., reporting submethods as calling methods, including their methodpath). Added tests covering the fix (see tests/submethods.test). - generic/nsfStack.c (CallStackMethodPath): Re-arranged the traversal slightly, to escape non-ensemble frames (eval CFRAMEs) as parts of the method path. Added test (see tests/submethods.test). - library/nx/nx.tcl: Corrected the impl of Ensemble->defaultmethod() (e.g., used self instead of current) - tests/disposition.test: Fixed test cases turned out to be false positives. Before the fixes, [current methodpath] gave non-empty results for simple object aliases.

- tests/parameters.test: Tracked down the relevant Tcl issue (fossil check-in 769801ace1) resulting in the bignum double-rounding problem, observed earlier. The work-around is setting the tcl precision level to 17. I made it applying conditionally, depending on the Tcl patch level as the work-around is not needed anymore fore 8.5.10+. - generic/nsf.c: Correct usage of TclDumpMemoryInfo() for changes in 8.5.10, introduced by fossil check-in 4a9ba46064. Memdebug builts (--enable-symbols=mem) therefore require a recent Tcl version (8.5.10+).

- generic/nsf.c / NsfOConfigureMethod(): Configure adds frames to its callstack context, however, so far the callstack modifications have not honoured the fact that configure() can be called from uplevel'ed call sites. The callstack context resulting from a prior uplevel was erased by the call frame introductions. As a consequence, parameter-dispatched methods found themselves in a wrong variable frame context. The suggested patch adds uplevel awareness in the most generic way I could think of. The entire test suite runs against the patched NsfOConfigureMethod(). However, I might be missing unwanted consequences for untested cases ... we need to think of further test scenarios ...
