Hi all,
I juect checked and abs~ and exp~ are indeed broken in 0.42-3 (and 0.42-4) - that got fixed in my source a few months ago but I haven't been releasing anything since there's a huge GUI re-write underway.
Here's the damage...
[msp@slash src]$ diff d_math.c ~/pd/src/d_math.c 630c630
< *out = exp(*in1);
*out++ = exp(*in1++);723c723
< *out = (f >= 0 ? f : -f);
*out++ = (f >= 0 ? f : -f);I think I have to try the latest GUI rewrite code (Hans-Christophe and Hannes are working on it and I'm basically just waiting for it to stabilize) -- and if it's not at least stable enough for me to put out as a "test" version, I should probably go back and apply all the applicable bug fixes I can find to 0.42 (a dangerous prospect since that process often seems to _introduce_ bugs as well as fix them!)
in this very case, i can confirm that the bugs are already fixed in Pd 0.42-5 (which - according to the SVN logs - was released in may 2009)
in this case i would consider upgrading Pd to the newest stable release.
apart from that i found that the SSE-code in zexy used for the zexy implementation of [abs~] is buggy as well. for whatever reasons, (recent versions(?) of) gcc always imply SSE, which makes the broken code somewhat mandatory.
since Pd>=0.42 will allow libraries to override its built-ins, you might eventually come across the [abs~] of zexy as well. in this case, please update zexy to the latest SVN as well.
