As a first step, I filed a bug for us for it:
https://gitlab.com/qemu-project/qemu/-/issues/2080

We should probably report this upstream, I suppose. It's
easy to reproduce without requiring the QEMU source tree:

mnementh$ mkdir htags-bug
mnementh$ cd htags-bug/
mnementh$ cat >hello.c
#include <stdio.h>

int main(void) {
    printf("hello world\n");
    return 0;
}
mnementh$ gtags
mnementh$ htags -anT
mnementh$ BIGVAR=$(perl -e 'print "x" x 100000') htags -anT
htags: Negative exec line limit = -80391
