Description Scott Lamb 2003-12-24 01:32:20 EST

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1)
Gecko/20031114

Description of problem:
The dmallocthcxx library, which is supposed to be a version of dmalloc
safe for multiple threads and C++, is apparently not. It claims to
become reentrant; I do not use it from within a signal handler, so the
only way this could happen is by not locking properly when used by
multiple threads simultaneously.

Version-Release number of selected component (if applicable):
dmalloc-4.8.1-12

How reproducible:
Always

Steps to Reproduce:
1. Download the soon-to-be-attached dmallocthcxx-crash.cc
2. Compile with gcc -Wall dmallocthcxx-crash.cc -o dmallocthcxx
-ldmallocthcxx -lpthread
3. Run with ./dmallocthcxx-crash

Actual Results:  $ ./dmallocthcxx-crash
debug-malloc library: halting program, fatal error
   Error: malloc library has gone recursive (err 11)


Expected Results:  Looping forever with no output

You might want to get the latest version of dmalloc (5.2.4) ... it
might fix things ... http://dmalloc.com

Comment 3 Jakub Jelinek 2004-10-19 10:23:32 EDT

Can't reproduce with dmalloc-5.3.0-3.
