Complexity measurement crashes: STEREO decoder

The BASOP STEREO decoder crashes, as reported by the Bi-Daily CI cmplx test: https://forge.3gpp.org/rep/sa4/audio/ivas-basop/-/jobs/419272. Based on the log file, the crash appears to occur during certain bitrate switching scenarios involving a frame erasure pattern: https://forge.3gpp.org/rep/ivas-codec-pc/ivas-codec/-/blob/main/ci/complexity_measurements/ep_10pct_fer.g192.

There is no error printed in the log file but the decoder ends prematurely in frame 2879. See the following:

To reproduce, use the script IvasBuildAndRunChecks.py or the following command-line tools:

scripts/prepare_instrumentation.sh -m MEM_ONLY
cd c-code_instrument
make -j
./IVAS_cod -stereo -max_band swb switchPaths/sw_highest.bin 32 ltv48_STEREO_32_STEREO.pcm bit
eid-xor -vbr -fer bit ep_10pct_fer.g192 bit_err
./IVAS_dec STEREO 32 bit_err out.wav

The input file is too large to be posted here but it may be re-generated using the script IvasBuildAndRunChecks.py.
