Bug#520689: libnspr4-0d: Failure when re-initializing the library

[Ludovico Cavedon]

Package: libnspr4-0d
Version: 4.7.1-4
Severity: normal

The libraries fails to reinitialize correctly after an
initialization/cleanup cycle.

Please see attached testcase.
If I run it I get the following output:

Init 1
Cleanup 1
success=1
Init 2
Cleanup 2

<deadlocked here>


If I set NSPR_LOG_MODULES=all:5, I get:
Init 1
-136541440[8ed2580]: Loaded library a.out (init)
Cleanup 1
-136541440[8ed2580]: PR_Cleanup: shutting down NSPR
success=1
Init 2
Segmentation fault

Thank you,
Ludovico
