Getting Segmentation fault (core dumped) while loading Extension about duckdb HOT 10 CLOSED

I can not reproduce this on a build on main with your reproduction.
Sounds like it's already fixed or there are additional details that are missing here to reproduce the issue.

from duckdb.

Can you share a few more details like:

• the result of PRAGMA platform
• the result of FROM duckdb_exceptions()
• what happens if you do:

import duckdb

con = duckdb.connect(database=':memory:')
con.load_extension('aaarrgh')

from duckdb.

@carlopi - I spun up an aarch64 ubuntu instance:

con.load_extension('aaarrgh')

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
duckdb.duckdb.IOException: IO Error: Extension "/home/ubuntu/.duckdb/extensions/v0.9.2/linux_arm64_gcc4/aaarrgh.duckdb_extension" not found.

Candidate extensions: "arrow"

excel is the name of the extension they're loading, not aaargh

@amplifinn-admin can you share the commands you used to build the excel extension for linux_arm64_gcc4?

I have downloaded manually excel.duckdb_extension.gz with this link: http://extensions.duckdb.org/v0.9.2/linux_arm64/excel.duckdb_extension.gz

import gzip
import shutil
import duckdb

with gzip.open('excel.duckdb_extension.gz','rb') as f_in:
with open('excel.duckdb_extension', 'wb') as f_out:
shutil.copyfileobj(f_in, f_out)

con = duckdb.connect()
con.install_extension('excel.duckdb_extension')

from duckdb.

con.load_extension('aaarrgh')

the result of PRAGMA platform ---> "linux_arm64_gcc4"
the result of FROM duckdb_exceptions() ---> Catalog Error: Table Function with name duckdb_exceptions does not exist!

Result for above mentioned code:

import duckdb
con = duckdb.connect(database=':memory:')
con.load_extension('excel')
Segmentation fault (core dumped)

The abi in that download isn't compatible with the python DuckDB binding, so a segfault here, while not ideal, isn't surprising

Thanks for reporting this. We already have in the roadmap implementing (some) checks before INSTALL and LOAD of extensions, that would have prevented this from happening but allow, on LOAD of a non compatible file, some error informing users that the file do not look like a compatible extensions.

I will close this for now, most relevant issue here is #8035, that is currently not planned.

@amplifinn-admin the platforms linux_arm64_gcc and linux_arm64 are different ones, see the list of our platforms. This causes the error.
