C API Seg Fault from OrtGetApiBase()->GetApi(ORT_API_VERSION);

[Jon-Croz]

Describe the issue

Initializing ORT with the C API breaks during code execution... including the headers and initializing other ORT functions seems fine except for: OrtGetApiBase()->GetApi(ORT_API_VERSION);.

Here is a small code snippet (there is more code that runs fine, but is not attached).

#define FUNCTION_NAME "Main:"
#include "assert.h"
#include "onnxruntime_c_api.h"
#include "header.h"

int main(int argc, char** argv)
{
  #define ORT_ABORT_ON_ERROR(expr)             \
  do {                                                                    \
    OrtStatus* onnx_status = (expr);                      \
    if (onnx_status != NULL) {                                 \
      const char* msg = g_ort->GetErrorMessage(onnx_status); \
      fprintf(outp, "%s\n", msg);                             \
      g_ort->ReleaseStatus(onnx_status);               \
      abort();                                                            \
    }                                                                        \
  } while (0);

  /* Problem is here... entering the ORT API ... */
  const OrtApi* g_ort = OrtGetApiBase()->GetApi(ORT_API_VERSION);

 }

Java and C# use the C API to initialize ORT and those are working fine in 1.17.1, so I think it's something to do with the exact C code you're using.
