+ debugging shared and/or C++ code. This is just a work-around until
+ we can transition to the new version of gdb completely. See below.
+
+/usr/gnu/bin/gdb:
+ This is the gdb from the ports area (if installed), also known as
+ gdb-4.11. There is a problem using gdb-4.11 to debug a core-file
+ generated by a binary which uses shared libraries. The problem is
+ basically due to the fact that the shared libraries are mmap'ed at
+ addresses in the memory space of the binary which are not accessible
+ to gdb-4.11 at the time that it tries to examine the core-file. This
+ usually manifests itself in "Cannot access memory at address <foo>"
+ messages at startup and "#0 <bar> in end ()" when you try to do
+ a backtrace ("bt").
+
+ Workaround: start gdb-4.11 without reference to the core-file,
+ e.g. "gdb fubar". Set a breakpoint in main and run the inferior
+ so that gdb-4.11 can resolve references to the shared libraries.
+ After this, use the "core-file" command to force gdb-4.11 to
+ load the core-file, e.g. "core-file fubar.core". Since all
+ shared library references were previously resolved gdb-4.11 can
+ now access the shared libraries and things like "bt" now work.
+ You will also be able to reference items previously on the stack
+ (from the core file), but all globals will show up as zero'd.
+ All these problems may be avoided if you compile the application
+ with -static.
+
+/sys/i386/isa/if_ep.c
+ The 3c509 driver will hang under heavy network loads and take your
+ machine off the network. (Though the machine will continue to run with
+ no network facilities)
+
+ Workaround: Try a "ifconfig ep0 down" and a "ifconfig ep0 up"
+ to get it running again.
+
+/sys/i386/isa/bt742a.c
+ The Bt445S and Bt747 controllers can cause problems when ISA DMA
+ is selected as an option. With the EISA controller the remedy is
+ easy - simply turn it off using your EISA configuration utility.
+ With the Bt445S, which is a VLB card, you must switch the undocumented
+ "SW10" on "SB2" to the off position. Also note that certain revisions
+ of the Buslogic board (Revision C or earlier, firmware revision <3.37)
+ will cause DATA CORRUPTION with systems containing more than 16MB of
+ memory. If you find this to be the case, temporarily remove your
+ extra memory and contact Buslogic for an upgrade!
+
+/usr/bin/find
+ find doesn't work on CDROM's. You need to call find with the
+ "fstype isofs" argument to get it working. The bug seems to be
+ in the "fts(3)" routines that find uses.
+
+/usr/bin/awk
+ awk dumps core for the following command line "awk '' blubber".
+ Problem is already known by the gawk maintainers and will be fixed
+ in the next release of gawk.
