SZ_STACK crash with debuginfo compiled in

[Dead2]

Reproduceable using Clang 14.0.5 and zlib-ng develop snapshot (probably the same with any version of zlib-ng really).

export SZ_CODE=0 SZ_LINK=0 SZ_HEAP=0 SZ_STACK=1 SZ_CLEAN=1
cmake -DCMAKE_VERBOSE_MAKEFILE=ON -DWITH_BENCHMARKS=OFF -DCMAKE_C_COMPILER=/home/hansr/github/stabilizer/szcc -DCMAKE_CXX_COMPILER=/home/hansr/github/stabilizer/szcc++ -DCMAKE_C_FLAGS="-g" .

Can be reproduced about 80% of the time by running this:
ctest . -j 10 --exclude-regex "benchmark.*" --progress --output-on-failure

There are two tests that typically fail, sometimes only one of them and sometimes neither.

[  FAILED  ] 2 tests, listed below:
[  FAILED  ] deflate.concurrency
[  FAILED  ] deflate_quick.bi_valid

Not much details available:

[ RUN      ] deflate.concurrency
/home/hansr/github/zlib/zlib-ng/test/test_deflate_concurrency.cc:146: Failure
Expected equality of these values:

    Which is: -3

Interesting that only these two tests repeatedly fails when we compile with -g, but none of the other 61 tests fail.
minigzip also fails, but less often, around 5-10% chance it seems like, at least on quite big files.

Note: SZ_CODE also fails 53/63 tests if enabled, but that seems to be an unrelated bug. I need to look at how to narrow that down to a cause.
