[Bug 881862] Re: svn up Segmentation Fault

[Marco Paolini]

ops sorry for the noise, it turns out it is a subversion 1.6.17 bug
(fixed in release 1.7.1 or maybe earlier):

subversion was using a local variable in stack for the callbacks
argument of sasl_client_new

but sasl_dispose was called outside this function, so when utils->log went looking for log callbacks
it was accessing some bogus memory area

the bad code is in subversion lib_ra_svn/cyrus_auth.c svn_ra_svn__do_cyrus_auth:
callbacks is a function local variable while it should live until sasl_dispose is called 

code in subversion 1.7.1 is correct: it allocates callbacks in heap

cheers,

Marco
