Hi,

I hope this is the right forum to post this bug I found. If not, let me know
and I'll repost.

Thanks,

----------------------------------------------------------------------------

platform      : win2k
boost version : 1_32_0
compiler      : g++ 3.3.1 (cygming special)
build         : both debug and release ( static linking of graphviz
library )

Symptoms:
1) Reading a digraph .dot file causes a syntax error to be emitted
2) The BGL example testcase has a false pass

This problem occurred in my BGL code, but to reproduce the problem, it is
easier to use the BGL example program example/graphviz.cpp, as annotated
below.

1) This step runs the graphviz testcase in <boost>\libs\graph\example.
Although
   I built both debug and released, I've retained only the relevant
"release" output.

h:\vault\boost\boost_1_32_0\libs\graph\example>bjam -d2 --preserve-test-targ
ets -sTOOLS=gcc -sBUILD="debug release <runtime-link>static" graphviz
      |  ...
      |  gcc-C++-action

      |

      |  gcc-Link-action
..\..\..\bin\boost\libs\graph\example\graphviz.test\gcc\debug\runtime-link-s
tatic\graphviz.exe
      |      "g++"   "-Wl,--enable-auto-image-base"   -static -g  -o
"..\..\..\bin\boost\libs\graph\example\graphviz.test\gcc\debug\runtime-link-

      |
      |  execute-test
..\..\..\bin\boost\libs\graph\example\graphviz.test\gcc\debug\runtime-link-s
tatic\graphviz.run
      |  ...

2) Note the **passed"" line.

      |  **passed**
..\..\..\bin\boost\libs\graph\example\graphviz.test\gcc\debug\runtime-link-s
tatic\graphviz.test
      |

3) This step shows running the testcase executable built above, manually,
showing the syntax error emitted.

      |
H:\vault\boost\boost_1_32_0\bin\boost\libs\graph\example\graphviz.test\gcc\r
elease\runtime-link-static>graphviz
../../../../../../../../../libs/graph/example/graphviz_test.dot
      | graphviz
../../../../../../../../../libs/graph/example/graphviz_test.dot
      | This is an example to demonstrate how to read graphviz file
      | and how to write graph to graphviz format.
      |
      |
      | Usage: graphviz  <input>.dot  <output>.dot
      | If only have one xxx.dot in command line,
      | the second dot is graphviz_test_new.dot by default.
      | If there is no input and output dot file in command line, input is
graphviz_test.dot and output graphviz_test_new.dot.
      | syntax error
      |

4) This step shows an equivalent VC7.1 build that runs correctly.

      |
H:\vault\boost\boost_1_32_0\bin\boost\libs\graph\example\graphviz.test\vc-7_
1\release\runtime-link-static>graphviz
../../../../../../../../../libs/graph/example/graphviz_test.dot
      | graphviz
../../../../../../../../../libs/graph/example/graphviz_test.dot
      | This is an example to demonstrate how to read graphviz file
      | and how to write graph to graphviz format.
      |
      |
      | Usage: graphviz  <input>.dot  <output>.dot
      | If only have one xxx.dot in command line,
      | the second dot is graphviz_test_new.dot by default.
      | If there is no input and output dot file in command line, input is
graphviz_test.dot and output graphviz_test_new.dot.
