alexcrichton opened PR #4964 from increase-stack-size to main:

This commit updates the MIN_STACK_SIZE constant for Unix platforms when allocating a sigaltstack from 16k to 64k. The signal handler captures a wasm Backtrace which involves memory allocations and it was recently discovered that, at least in debug mode, jemalloc can take up to 16k of stack space for an allocation. To allow running the sigaltstack size is increased here.
