Crash in fbclient after unsuccessful user management API call

Created: 12/Sep/07 09:58 AM   Updated: 19/Jan/16 05:01 AM
Component/s: API / Client Library
Affects Version/s: 2.0.0, 2.0.1, 2.0.2
Fix Version/s: 2.1 Beta 2, 2.0.4

QA Status: No test

 Description  « Hide
Any unsuccessful user API call (e.g. isc_add_user() called for an already existing user name) returns invalid status vector with string arguments pointing to the deallocated memory. If the client application then performs any of the error handling API calls (isc_interpret() etc), SEGV happens.

Reported by Guido Klapperich.

I suppose the bug is located in alt.cpp::executeSecurityCommand() where the detachRemoteServiceManager() call discards the status strings.

Added dedicated circular buffer to keep strings permanently.
