Description Joe Orton 2003-01-30 13:40:17 UTC
Description of problem:
ElectricFence dumps core on Hammer immediately at startup.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
$ ef ls

anything linked against -lefence does likewise, as does running the test suite
in the EF sources.

Actual results:

  Electric Fence 2.2.0 Copyright (C) 1987-1999 Bruce Perens <bruce@perens.com>
/usr/bin/ef: line 20:  1132 Segmentation fault      ( export
LD_PRELOAD=libefence.so.0.0; exec $* )

Expected results:
No segfaults.

Additional info:
EF test suite passes if not compiled with -DUSE_SEMAPHORE.
From adding debugging, the segfault occurs in exactly the pthread_self() call in

Comment 1 Joe Orton 2003-01-30 13:57:57 UTC
(As an aside, efence.c seems to assume 0 isn't a valid pthread_t, which I don't
believe is correct, and it probably should be using pthread_equal rather than !=
to compare pthread_t values.  Neither of these seem to be the cause of the
segfaults, however.)

Comment 2 Jakub Jelinek 2003-02-04 16:42:31 UTC
Should be fixed in ElectricFence-2.2.2-15.

Comment 3 Joe Orton 2003-02-04 16:55:33 UTC
Thanks Jakub, works fine for me now.
