Subject: [Bug libgcj/28263]  New: [win32] Memory Leak In Cleaning Exception Handling Contexts
Date: Wed, 05 Jul 2006 02:03:00 -0000	[thread overview]
Message-ID: <bug-28263-8271@http.gcc.gnu.org/bugzilla/> (raw)

There is a leak of 24 bytes of exception handling context per Java thread on
MinGW due to a hack that fools the MinGW runtime into thinking that
multi-threaded exception handling is in effect but avoids linking to the
correct __mingwthr_key_dtor() from mingwm10.dll and instead links to a dummy
version from libmingw32.a.

  http://gcc.gnu.org/ml/java/2006-07/msg00017.html

A workaround for avoiding this leak is to explicitly use -mthreads while
linking Java programmes with GCJ.
