bug#16641: Assert triggered (hashtab.c:137) - Guile-2.0.9

[Cole Minaar <cole.minaar@concurrent.co.za>]

Hi,

We have a system running and was fine for about a month, all the code paths should have been exercised, and the system then threw an assert when it was not processing any requests.

The system runs in a loop and reads values from a database, and also forces a garbage collect every so often.

The assert error thrown:
Assertion failed: removed <= len, file hashtab.c, line 137

The following libraries are used:
gcc             4.7.2   
bdw-gc          7.2     
libtool         2.2.10  
gmp             5.0.2   
libiconv        1.14
libunistring    0.9.3   
libffi          3.0.10  
readline        6.1
guile           2.0.9   
guile-lib       0.2.2   
guile-dbi       2.1.5   
mysql           5.1.53  
guile-dbd-mysql 2.1.4

If you have any suggestions I would be glad to hear.
