cpp-peglib crash - Githubissues

I can't get cpp-peglib to work on my new system.

I'm using cpp-peglib/master (11ed83e46fb0268c22005a6b8a9f094f8ea7208c), G++ 10.2.0 and/or clang++ 10.0.1, glibc 2.32, on Linux x86_64.

I compiled this minimal piece of code:

#include "cpp-peglib/peglib.h"

int main() {
    peg::parser parser(R"(
        ROOT  <- _ TOKEN (',' _ TOKEN)*
        TOKEN <- < [a-z0-9]+ > _
        _     <- [ \t\r\n]*
    )");
    return 0;
}

But it crashes when I run it:

terminate called after throwing an instance of 'std::system_error'
  what():  Unknown error -1
fish: “./test” terminated by signal SIGABRT (Abort)

Valgrind shows the following stack trace:

I can't figure out what's wrong. Any ideas?
