Crash at launch on macOS 26 — infinite recursion in SecKeychainFindGenericPassword / HSMasterPasswordHelper

[digikaizen]

Bug Report: Crash at launch on macOS 26

Environment

• App: SQLPro for MSSQL
• Version: 2026.07 (115707.5)
• macOS: macOS 26.4 (25E246)
• Hardware: Apple Silicon (ARM-64, Mac17,8)

Description

The app crashes immediately at launch every time. It is not possible to get past the startup screen. I have already tried:

• Clearing Keychain entries for SQLPro / hankinsoft via Keychain Access
• Running defaults delete com.hankinsoft.osx.tinysqlstudio in Terminal

Neither resolved the issue.

Crash Summary

The crash is caused by infinite recursion (7,452 levels deep) triggered at startup when the app attempts to initialize HSMasterPasswordHelper and access the Keychain via SecKeychainFindGenericPassword. A CSSMError is thrown (via ldapdl) and caught in a loop that never terminates, eventually overflowing the stack.

Exception: EXC_BAD_ACCESS (SIGSEGV) — Thread stack size exceeded due to excessive recursion

Key stack frames:

CSSMError::ThrowCSSMError → LDAPDatabase::DbDataGetFirst → SecKeychainFindGenericPassword
→ [PDKeychainBindings objectForKey:] → [HSMasterPasswordHelper sharedInstance]
→ [SQLPro applicationDidFinishLaunching]
→ __cxa_rethrow [recursion x7452] → CRASH

The SecKeychainFindGenericPassword API (accessed via ldapdl) appears to be broken or unsupported on macOS 26, and the exception handler in the app is rethrowing the error in an infinite loop rather than gracefully handling the failure.

Steps to Reproduce

1. Install SQLPro for MSSQL 2026.07 on macOS 26.4
2. Launch the app
3. App crashes immediately — no UI is shown

Expected Behavior

App should launch normally and handle a missing or inaccessible Keychain entry gracefully.

Notes

This appears to be related to the deprecation of legacy CSSM/Keychain APIs in macOS 26. The SecKeychainFindGenericPassword path through ldapdl is no longer functioning correctly. Migrating to modern Keychain APIs (SecItemCopyMatching) should resolve this.

Investigating.

Hello Kyle, Thanks for your reactivity and quick response. Would you have a Url for the previous version ? Indeed, when trying to download from the website I got package “SQLProMSSQL.2026.07.app.zip” ? I still could reproduce the issue with that version downloaded from the website. I could not find any list of previous versions to access to.

This is very helpful. The crash is caused by the legacy SecKeychainFindGenericPassword API (accessed through PDKeychainBindings) entering an infinite recursion on macOS 26. This is a known compatibility issue with the older CSSM-based Keychain APIs on newer macOS versions. We are investigating the fix. In the meantime, if you need immediate access, you can try downloading the previous version from the website (rather than the App Store) as a temporary workaround. We will update this issue when a fix is available. — Reply to this email directly, view it on GitHub<#1112?email_source=notifications&email_token=AOZOEHHB742XT7A24EFFIDD4T22I5A5CNFSNUABFM5UWIORPF5TWS5BNNB2WEL2JONZXKZKDN5WW2ZLOOQXTIMJXHE4DQNZUGQ22M4TFMFZW63VGMF2XI2DPOKSWK5TFNZ2KYZTPN52GK4S7MNWGSY3L#issuecomment-4179887445>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/AOZOEHDO5KPFQBCV6M5CJJT4T22I5AVCNFSM6AAAAACXK562M2VHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHM2DCNZZHA4DONBUGU>.

A previous version is at https://sqlprostudio.s3.us-east-1.amazonaws.com/mssql/SQLProMSSQL.2025.51.app.zip. Just wondering if you happen to have a full stack/crash report for when this crash happens? If possible could you attach that here?

Could you grab and try this build?
https://sqlprostudio.s3.us-east-1.amazonaws.com/mssql/SQLProMSSQL.2026.60.app.zip

If that still causes an issue, can you please post the crash log - note that files do not attached via email so you may need to navigate directly to the GitHub issue.

[digikaizen]

Just gave it a try. Please find attached the .ips from the crash.

hmm, ips is not coming through. Could you possibly email it to kyle@hankinsoft.com?

[hankinsoft]

Any chance you could try this version:
https://sqlprostudio.s3.us-east-1.amazonaws.com/mssql/SQLProMSSQL.2026.61.app.zip

And again, if it happens to crash provide the ips to kyle@hankinsoft.com?

Still crashing from my side on that version. Please find attached the .ips.
