Hallo!
I encountered this problem in the destructor of flext/readanysf~ (latest from cvs - simply wanted to delete readanysf~):

I have no idea where the problem should be ... if it's a flext or readanysf~ issue ...

please define FLEXT_NOGLOBALNEW when compiling readanysf~

please define FLEXT_NOGLOBALNEW when compiling readanysf~
it is defined !
can you compile readanysf~ with debugging symbols and link with the flext debugging library (libflext-pd_d)?

Hallo tim!

okay:
now, with debugging symbols, the same patch results in a SEGFAULT: ---------8<------------ Starting program: /usr/bin/pd -path /usr/lib/pd/externs -path abs -lib Gem -lib PDContainer -lib zexy -lib iemlib1 -lib iemlib2 main.pd [Thread debugging using libthread_db enabled] [New Thread -1209653568 (LWP 29931)] OSS: requested audio buffer size 8820 limited to 2048 [New Thread -1228325968 (LWP 29962)] [New Thread -1237460048 (LWP 29963)] [New Thread -1245848656 (LWP 29964)] [New Thread -1254237264 (LWP 29965)] [Thread -1237460048 (LWP 29963) exited]

what is maybe important: I use pd0.39-0test6, but had to compile against the header files of pd-0.38-4 (because of the "template" stuff ...)

you cannot expect flext / flext externals to work if compiled against the wrong headers... i'm about 99% sure, that it's related to that ...

Hallo!
I use pd0.39-0test6, but had to compile against the header files of pd-0.38-4 (because of the "template" stuff ...)
forgot to comment on this: this issue is easily fixable... just replace "template" by "waldheim" or anything else.
it's gone in test7 ... (so I don't have to use waldheim ;)
LG Georg
Hallo!
unfortunately still the same behaviour (compiled now pd0.39-test7 and recompiled flext and readanysf)
