Sorry, made a change after sleeping on the patch -- realised that I was storing a GAP string in a C structure which might get garbage collected! Now using copy of string in a structure which I know won't get GCed. |

Ahh, that's quite subtle -- good thinking :) |

Can you perhaps edit the commit message and elaborate; e.g. copy the description of this PR, perhaps add the note in your last commen? |
This patch ensures when reopening a file we check if the filename has been opened previously, and if so associate it with the same filename number. This is tested in the 'profiling' package, which is why there is no tests here.

Better commit message. Also since writing this I've put tests into the profiling package to check reading a file multiple times works. |

This patch makes profiling correctly handle the same file being opened multiple times, by associating it with the same integer filename.
This is unfortunately hard to automatically test -- but I've tested it manually for a few tests and it works fine (the profiling should have a better automated testsuite...).
This doesn't require a change in profiling, and should work with any version.
