Hmm - that is interesting, thanks.
We typically work with 4.1.2, 4.6.1 and 4.7.1 so it looks like I missed the versions in between. - Piotr

The workaround was to build with -O2. gcc 4.6
and up seem ok. I didn't test with gcc 4.5.
Unfortunately, I didn't have time to dig any deeper as to whether this was an actual optimizer bug, or whether there are some spurious assumptions in the code leading to it. Just something to keep in mind. - ½ On 13-06-17 09:35 PM, Piotr Stanczyk wrote:
