When this happens, the error message is confusing to the user. This can also happen under normal build if the executable name contains double quite, which is unlikely though. We fix this issue by introducing escaping for double quotes inside a string by repeating it twice. We also fix a buffer overflow bug when the length of the string happen to be multiple of 5000. Test Plan: new tests, which used to fail with error message: ``` hp2ps: "T15904".hp, line 2: integer must follow identifier ``` use new ghc and hp2ps to profile a simple program.

It seems like `$'string'` is not recognized under all test environments, so let's avoid it in tests.
