Segmentation fault when a segment is missing from minio

[himsheda]

Describe the bug

When a segment is corrupted or deleted from minio, if you try to read data in that date range, then the code will throw an segmentation error inside the C++ instead of raising a DataError.

I was using 4.4.3 earlier, it works correctly. But the recent version does not work. I tried upto 6.2.1. Not sure the exact version which had this bug for the first time.

Steps/Code to Reproduce

Create a data frame with a date range and write the data into minio backend.
Then delete a segment from tdata.

Then when you try to read the data it will now return a data error instead it will throw you a segmentation fault, hence crashing your application completely

Expected Results

DataError

Hi @himsheda, can you please provide:

• a self-contained minimal code snippet (including library creation) that writes the data
• the path of the tdata key(s) you are removing
• a self-contained minimal code snippet that reads the data and segfaults
