I upgraded libc6 to 2.3.2-4. While the original segfault seems to be fixed, I get a different one at a later stage after ICA loads, so it's still useless for me. Not sure if this is a bug in ICA 7.0 or in glibc. Starting program: /usr/citrix/wfica (no debugging symbols found)... (no debugging symbols found)... Program received signal SIGSEGV, Segmentation fault. 0x401cedd3 in free () from /lib/libc.so.6
