() Removing QtCore or libcurl from the link line generates a successfully running program.   Removing just TBB proxy (that enables the TBB allocator) also generates a successfully running program.

I am developing a linux application in C++, which uses Qt 4.7.3 LGPL version, libcurl 7.24.0 and TBB(but not it's memory allocator). It might be too early to say, but I haven't faced any issue yet. -lijo ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette:  http://curl.haxx.se/mail/etiquette.html
