I have two bugs to report, both concerning macros and both occuring in 1.04 and
in 1.1.2
Incidentally, I'm no longer on any lyx mailing list, so send any queries direct
to me.
Best wishes,
Angus

1.usability:
--------
I can define macros and use them to create equations quickly. However, when I
come to create output using view dvi, latex complains that these control
sequences are unknown. The only remedy I've found is to edit the lyx file by
hand, cut out the macros, and reinsert them in the latex preamble as straight
'newcommands'. In this case, I can't use them within lyx to create my equations
because lyx doesn't recognise that they need arguments.
I attach two files to illustrate what I mean:
bad_tex.lyx is good as lyx (I can edit my equations using the macros) but tex
then complains.
good_tex.lyx is identical save for the macros being removed and placed in the
latex preamble. This now produces a valid tex file, but is useless as lyx.
good_tex.lyx, everything appears to work correctly BECAUSE lyx's macros are
defined for all documents. Surely, macros are document specific!!!
2. crashes
--------
both 1.04 and 1.1.2 crash A LOT. One particular instance concerns
macros.
Running a non-stripped version of 1.1.2 under gdb on a DEC Alpha running
Digital Unix 3.2
Clicking on any of the macros in bad_tex.lyx (or indeed in the User's Guide!)
(eg to edit them) causes a segmentation fault:
Program received signal SIGSEGV, Segmentation fault.

This is true whether or not math_draw.C was compiled optimised or not.

warning: Hit heuristic-fence-post without finding
warning: enclosing function for address 0x794c335f5f657372
This warning occurs if you are debugging a function without any symbols
(for example, in a stripped executable). In that case, you may wish to
increase the size of the search with the `set heuristic-fence-post' command.
Otherwise, you told GDB there was a function where there isn't one, or
(more likely) you have encountered a bug in GDB.
