it claimed to fix, but caused an incorrect DRC maxwidth check
instead. The problem appears to be correctly resolved now.
Also: Tracked down a recently-introduced minor issue in which
the interactive DRC stops running after issuing "drc check" and
does not resume until another key or mouse even occurs. This
turned out to be caused by the work on the "logcommands" command,
which should have used "*bypass" before "logcommands suspend"
and "logcommands resume", since the "*bypass" indicates that
the command has no impact on layout and should not interrupt
the DRC checker.
respect to using the 3rd mouse button to hide a layer, and
indicating the layer is hidden by blanking the icon (which works
better with the new scrollable icon list, but got broken by the
same). Also: Added a previously missing behavior, which is to
correctly update the icon settings based on using the command
"see" and "see no" with layer aliases (e.g., "allm1").
request #325 from Daryl Miles. Made a few simple style changes
to conform to (what is vaguely defined as) the overall programming
style for magic (passed down from John Ousterhout).
The main cause of the crash was the path for UNDO_CELL_PLACE this was
trigged by performing a number of cell create/move operations (unknown
exactly what sequence). Then a large number of "undo" operations.
There is an ASSERT in findUse() but that does not seem built into the
release (or debug CFLAGS=-g3) builds.
This is a defensive fix, might cause unexpected program exit if triggered.
The loop will iterate at least once when nbytes==0, but this value
indicates XLookupString did not fill in any data, so the entire buffer
is undefined.
Using memset() before or inChar[0]=0 after XLookupString did not fix
the issue. Using inChar[0]=0 immediately before the loop did fix as
well. But this patch seems to be the best approach.
This function is related to libreadline rl_pre_input_hook callback
which is invoked as (not making use of any function return value):
readline.c: (*rl_pre_input_hook) ();
The general prototype for this function is:
rltypedefs.h:typedef int rl_hook_func_t PARAMS((void));
So the resolution is to provide a known value as the return value, which
resolves the concern.

It is usual for a pointer to require the largest width, while some
platforms might have an 'int' that is smaller than a pointer width.
This reverses the detection order to find.
Note since C99 there is <stdint.h> with type 'intmax_t' which
serves a similar purpose.
SonarCloud reports a concern with this on many lines where used.
"An integral type is too small to hold a pointer value."

This is technically a false positive as grClipPoints() will always
initializes a value to ok1 and ok2 when called. The function is in
the same compile unit, so probably the compiler can see this as well
and potentially not perform the initiailization begin performed in
this commit.
But to quieten and remove this item from the analysis report
assigning an initialization value.

graphics/grClip.c:451 Branch condition evaluates to a garbage value
https://sonarcloud.io/project/issues?open=AZJB160MNGfDNup0Rit4&id=dlmiles_magic
Looks like old code. Looks like local variable 'j' could be removed.
Initialization lowers the severity of concern in this area.
The 'j' variable is now written but never read.

The left expression of the compound assignment is an uninitialized value. The computed value will also be garbage

This resolution assumes that all records and values of ch->gcr_type are expected
to be one of the 3 cases in the switch. The bug it on the first iteration it is
possible 'tot' and 'clear' is just not initializaed and on a subsequent iteration
it is possible it ot setup to the previous interation values.

garouter/gaChannel.c:385:3rd function call argument is an uninitialized value

An FEOF exit path exists in READRH() which causes the output
variable(s) to not be assigned a value, then the code makes
a decision (branch) based on uninitialized data.
