UPDATE: bug was seemingly fixed by adding an invariant condition to the merge function with excludes subparsers with the error action. Further testing is needed before closing this.
The error occurs on the following code snippet:
#ifdef A
typedef int a;
#endif
#ifdef B
typedef int b;
#endif
#ifdef C
typedef int c;
#endif
struct y
{
#ifndef A
a i;
b j;
#endif
#ifdef B
c k;
#endif
};
int main()
{
#ifdef B
int d = 2;
#else
int d = 2;
#endif
return 0;
}
What we see is that the parser forks on #ifdef C, and then does not merge on struct. From here we see the !defined C branch fork as follows:
forked 1 into 3 parsers
(!(defined C), (#if !(defined A)
, REDUCE, 179, 22, !(defined C)):[(}, SHIFT, 623, 0, (defined A) && !(defined B) && !(defined C)), (a, ERROR, 0, 22, !(defined A) && !(defined C)), (c, ERROR, 0, 30, (defined A) && (defined B) && !(defined C))])
--into--
(!(defined A) && !(defined C), (a, ERROR, 0, 22, !(defined A) && !(defined C)))
((defined A) && (defined B) && !(defined C), (c, ERROR, 0, 30, (defined A) && (defined B) && !(defined C)))
((defined A) && !(defined B) && !(defined C), (}, SHIFT, 623, 0, (defined A) && !(defined B) && !(defined C)))
However we see the defined C branch for as this:
forked 1 into 2 parsers
((defined C), (#if !(defined A)
, REDUCE, 179, 22, (defined C)):[(}, SHIFT, 623, 0, (defined A) && !(defined B) && (defined C)), (a, ERROR, 0, 22, !(defined A) && (defined C)), (c, SHIFT, 24, 0, (defined A) && (defined B) && (defined C))])
--into--
(!(defined A) && (defined C), (a, ERROR, 0, 22, !(defined A) && (defined C)))
((defined A) && (defined C), (#if !(defined A)
, SHIFT, 623, 22, (defined A) && (defined C)):[(}, SHIFT, 623, 0, (defined A) && !(defined B) && (defined C)), (c, SHIFT, 24, 0, (defined A) && (defined B) && (defined C))])
What's interesting here is that the second branch stays on the same token. Although both parsers seem to have the same look ahead conditions. We then see a merge action occur after some type errors.

This leaves the potential valid subparser with condition !A && B && C unexecuted, and therefore unrepresented. The following is the entire output:
