Types are confused in inlining

[Gary Oblock <gary@amperecomputing.com>]

I'm not accusing inlining of having problems but I really
need to understand what's going on in this situation so I can
fix my optimization.

The error given is:
main.c: In function ‘main’:
main.c:5:1: error: non-trivial conversion in ‘ssa_name’
    5 | main(void)
      | ^
struct type_t *
unsigned long
_101 = dedangled_97;
during GIMPLE pass: fixup_cfg
etc.
etc.

I put a conditional breakpoint in gdb where both
_101 and dedangled_97 were created and low
and behold they were both set to "unsigned long".
Does anybody have a clue as to how "_101" got
changed from "unsigned long" to "struct type_t *"?
Note, the later is a meaningful type in my program.
I'm trying to replace all instances of the former as
part of structure reorganization optimization.) I should
mention that this GIMPLE stmt is the one that moves
the value computed in an inlined function into the body
of code where the inling took place.

Thanks,

Gary Oblock
