Bug#324526: Compiling and linking Verilog simulations with VCS 7.2 does not work after libc6 upgrade



Package: libc6
Version: 2.3.5-3
Severity: normal

After upgrading libc6 (from 2.3.2.ds1-22) to 2.3.5-3 I am no longer able to compile and link Verilog simulations with Synopsys VCS. The problem appears to be missing symbols in libc6. The error messages I get are as follows:
gcc   -o ../simv  5NrI_d.o 5NrIB_d.o KDF7_1_d.o SIM_l.o   /tools/vcs7.2.new/vcs7.2/gui/virsim/linux/vcdplus/vcs7_2/libvirsim.a     /tools/vcs7.2.new/vcs7.2/linux/lib/libvcsnew.so     -ldl  -lc -lm -ldl

Downgrading libc6 (and reverting most of my system to testing to fix dependencies)
works around the problem, but that does not seem like a long-term solution.
