The single error node smooshes everything into a single atom, breaking diff.
Simplifying pretty much anything in the example produces a much more usable output without an error node, e.g. removing one of the .c in L15:
.c
static void foo(void) { #if FOREVER while (1) { #endif foo(); #if FOREVER } #endif } static void bar(void) { if (1) { var = (func(a, a.b) + a.b.c); } else { var = func(a, a.b) + a.b + a.b.c + a.b.c + a.b; } }

There seems to be some form of limit at play here that produces an error node over a certain code complexity.
The output of tree-sitter parse in tree-sitter-c v0.20.4 looks good in both cases, so it seems to be a difft thing.

The following file, which is parsed incorrectly by tree-sitter-c due to tree-sitter/tree-sitter-c#108:
Produces these
--dump-ts/--dump-syntaxoutputs:difft dump output
The single error node smooshes everything into a single atom, breaking diff.
Simplifying pretty much anything in the example produces a much more usable output without an error node, e.g. removing one of the
.cin L15:difft dump output
