thick space in latex formula causes error

[ajmay81]

i.e. the \; latex command in math mode. This is a regression in Doxygen 1.10.0, it did not occur with 1.9.8. An example Fortran file test.f90:

!> test doxygen
!>
!> some formula \f$U^{\;\;i_1}_{ac}\f$ included.
subroutine test
end subroutine test

Generates:

/host> doxygen Doxyfile 1>/dev/null
/host/test.f90:4: warning: End of comment block while inside formula.
********************************************************************
Error in file /host/test.f90 line: 6, state: 10(ModuleBody)
********************************************************************

This was with doxygen built from doxygen-1.10.0.src.tar.gz.

Looks like:
b6018c3 is the first bad commit

I've just pushed a proposed patch, pull request #10557

[albert-github]

Code has been integrated in master on GitHub (please don't close the issue as this will be done at the moment of an official release).

[doxygen]

This issue was previously marked 'fixed but not released',
which means it should be fixed in doxygen version 1.11.0.
Please verify if this is indeed the case. Reopen the
issue if you think it is not fixed and please include any additional information
that you think can be relevant (preferably in the form of a self-contained example).

[ajmay81]

I don't know if this warrants a new issue or if it's a continuation of this one, but a semi-colon after a formula causes trouble. An example test.f90:

!> test doxygen
!>
!> A formula \f$A\f$; followed by a semi-colon
subroutine test
end subroutine test

Generates:

/host> doxygen Doxyfile 1>/dev/null
********************************************************************
Error in file /host/test.f90 line: 6, state: 10(ModuleBody)
********************************************************************
/host> doxygen --version
1.11.0

There is no such problem if the semi-colon is changed to a comma.

@ajmay81 Please create a new issue for this.
