DrMemory crashing with my program

_From [mi...@avast.com](https://code.google.com/u/105052097180627951457/) on July 13, 2014 18:42:16_

> What steps will reproduce the problem?
1. Running command "drmemory ex_html.exe" (the program is small and attached).
(The analyzed program is buggy: that's why I want to use DrMemory with it.)
2. After quitting the analyzed application, DrMemory shows message box informing
me about a crash. (Unfortunately text from it cannot be copied and it is too
long to type manually so see attached screenshot.) After that notepad with
the report shows but it contains only 4 lines:

Dr. Memory version 1.7.0 build 5 built on Apr 4 2014 23:38:05
Dr. Memory results for pid 3628: "ex_html.exe"
Application cmdline: "bin/ex_html.exe"
Recorded 104 suppression(s) from default c:\DrMemory-1.7.0-5\bin\suppress-default.txt

> What is the expected output? What do you see instead?

DrMemory should provide complete analyzes report and it should not crash.

> What version of the product are you using? On what operating system?
- DrMemory 1.7.0-5
- Windows 8.1 (64-bit)

> Does the problem go away when running in light mode (pass "-light" to Dr.
> Memory)? What about when running with the options "-leaks_only
> -no_count_leaks -no_track_allocs"?

Yes, it goes away in all those cases. It does not find any issue in the analyzed
program.

> Does the problem go away when using the most recent build from
> http://build.chromium.org/p/client.drmemory/builds/? Tried several most recent builds for Windows. They do not work for me at
all. (They exit immediately without running the specified program and
without generating any report.)

Error message box appears. It says this:

Application d:\prj\mctrl\bin\ex_html.exe (4236) DynamucRIO usage error
: instr_encode error: no encoding found (see log)

(Logs attached)
