The bug pertains to the unwrapping of strings. A string that should not
have been unwrapped was stripped of it's quotes, leading to this
situation :
Correct evaluation :
=IF(MFCO5<0, CALL("urlmon","URLDownloadToFileA","JJCCBB",0, (...)
Evaluation prior to fix :
=IF(MFCO5<0, CALL("urlmon","URLDownloadToFileA,"JJCCBB,0," (...)
because the string ","JJCCBB" was being stripped to "JJCCBB
This caused an error in the parsing of the formula, crashing the
program.
To fix it, I have change the unwrapping function to avoid unwrapping
when the count of quotes is uneven
