Compilation failure with GLIBC 2.34+ #4
Description
Hi,
The build of CancerInSilico fails on Linux at Bioconductor since a while:
g++ -std=gnu++17 -I"/home/biocbuild/bbs-3.18-bioc/R/include" -DNDEBUG -I'/home/biocbuild/bbs-3.18-bioc/R/site-library/Rcpp/include' -I'/home/biocbuild/bbs-3.18-bioc/R/site-library/BH/include' -I/usr/local/include -fpic -g -O2 -Wall -c test-runner.cpp -o test-runner.o
In file included from /usr/include/signal.h:328,
from Tests/catch.h:6450,
from test-runner.cpp:2:
Tests/catch.h:6473:33: error: size of array ‘altStackMem’ is not an integral constant-expression

ERROR: compilation failed for package ‘CancerInSilico’
It is because SIGSTKSZ is no longer a constant in glibc 2.34+, so it cannot be used as a size of an array allocation.
Some people solved the problem by dynamically allocate the array: doctest/doctest@8ee91f3
Please let me know if you'd be interested in applying such fix and I can send it as a Pull Request!
Thank you!
