Is anybody else experiencing huge slowdown in the latest version?

I understand gradual slowdown due to larger feature set, but not a ten-fold slowdown.

My project is mid-size, 180.000 lines of C code.
My command line is:
cppcheck --max-configs=1 --enable=all --std=c99 .c .h

The slowdown is extreme on larger modules (>20.000 lines)

cppcheck 1.83
real 1m7.098s
user 1m7.048s
sys 0m0.048s

cppcheck 2.3
real 1m36.737s
user 1m36.415s
sys 0m0.072s

cppheck 2.5
real 16m1.705s
user 16m1.356s
sys 0m0.093s

My system in Linux, i7 CPU has 6 cores / 12 threads, 16 GB of RAM on SSD disk.
For size and copyright reasons, can't share the code... or make a small example.

I'm seeing similar problems. I have created this ticket with example code.
