Hi,
Thanks in advance for any assistance, my situation is as follows:
I'm using valgrind 3.4.1 under Fedora 11, profiling code written in assembly
(intel syntax), compiled with nasm 2.05.01 and linked with ld
2.19.51.0.14-1.fc11 20090722.
The valgrind/cachegrind seems to operate fine but when attempting to annotate I
get a 'divide by zero' error. No results found via web search for the error
meassage so I thought maybe assembly/intel syntax source was not supported but
couldn't find anything obvious in the valgrind doco. Here's a sample session
output:

I took a quick look at cg_annotate and thought possibly there were no functions
found ? Happy to post the source if that helps (amateur alert)
thanks
