Richard,

I noticed you had some discussions over at CodeSourcery about compilation failure due to the naked attribute.&nbsp; Basically, the xQueueSendFromISR() fails and produces a compiler error as:  
uart/uart0ISR.cpp:66: internal compiler error: in expand\_expr\_addr\_expr\_1, at expr.c:6858

Your discussiosn:  
[http://www.codesourcery.com/archives/arm-gnu/msg02523.html](http://www.codesourcery.com/archives/arm-gnu/msg02523.html)

I’m having this problem and while I’m sure this is a CodeSourcery GCC issue (since GNUARM 4.3.2 works fine), I just wanted to find out if a resolution was reached.&nbsp; Apparently, the latest Lite version of CodeSourcery still has this problem.&nbsp; Is there something that can be done with FreeRTOS code to avoid this problem, or is this a bug that should be filed with CodeSourcery?

Thanks,  
Preet

It was a bug that had been introduced into that version of CodeSourcery’s GCC - I thought it had since been fixed.&nbsp; The code was indeed valid ARM code.

Regards.
