flirc_util.exe behaviour in version 3.26.8

[ffwema]

I have a batch script that utilizes flirc_util.exe to send IR commands with Flirc USB. After upgrading Flirc (by replacing Flirc.exe & flirc_util.exe in the install dir) from 3.26.5 to 3.26.8 (because I need support for Pronto IR codes), I am having the following issue. If flirc_util.exe command is inside a for /f loop, for example:

for /f "delims=" %%a in ('""C:\Program Files (x86^)\Flirc\flirc_util.exe" sendir --pronto="0000 006d 0022 0002 0156 00ab 0015 0040 0015 0040 0015 0040 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0015 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0015 0015 0015 0015 0015 0015 0040 0015 0015 0015 0040 0015 0015 0015 0015 0015 0040 0015 0040 0015 0040 0015 0015 0015 0040 0015 0015 0015 0040 0015 0040 0015 0015 0015 05d8 0156 0055 0015 0e48" 2>&1"') do echo %%a

the IR signal is NOT being sent anymore. flirc_util.exe command output is still displayed though:

Done!

If flirc_util.exe command is called directly, for example:

"C:\Program Files (x86)\Flirc\flirc_util.exe" sendir --pronto="0000 006d 0022 0002 0156 00ab 0015 0040 0015 0040 0015 0040 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0015 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0015 0015 0015 0015 0015 0015 0040 0015 0015 0015 0040 0015 0015 0015 0015 0015 0040 0015 0040 0015 0040 0015 0015 0015 0040 0015 0015 0015 0040 0015 0040 0015 0015 0015 05d8 0156 0055 0015 0e48" 2>&1

the IR signal is still being sent (most of the time anyway*).

(both examples can also be verified directly in cmd.exe if you replace %%a with %a)

Can somebody please help. Thank you in advance.

Regards,

* After some experimenting it seems like the longer (more complicated) the command line is, the less likely the IR signal will be sent. Very strange.
