Windows bash script hangs but shell runs

[chancyk]

OS : Windows 11 Pro Cosmos: 3.1.3 Cosmocc: 3.1.3

I'm trying to compile a Nim C file with cosmocc which works fine from within the bash shell, but hangs indefinitely if I invoke the same command from a script like:

export PATH="/C/Bin/cosmos/bin:/C/Bin/cosmocc/bin"
cd /C/Bin/cosmocc
./bin/cosmocc $*
exit 0

With --strace, cosmocc seems to churn indefinitely on:

SYS  15840  13036      2'041'625'954 readlinkat(AT_FDCWD, "C:/", [""]) → -1 EINVAL

And --ftrace:

Any ideas what might be going on here?
