Summary: Debug4x: Application locks at start Product: Wine Version: 1.3.21 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: stefano.priore@inwind.it
Debug4x is a free development environment for the 48/49/50 series of HP calculators.
Current available version at http://www.debug4x.com/ (v2.2 - build 159) hangs after a successful installation during first launch.
I've tried to obtain a backtrace as suggested at http://wiki.winehq.org/Backtraces?action=show&redirect=winedbg - I'll attach soon the (very short) report.

That's all the output I've been able to extract from running winedbg. My attempts to "attach" to the pid of Debug4x to obtain a more complete backtrace failed due to the fact that "attach" is not a recognized command, despite what http://wiki.winehq.org/Backtraces?action=show&redirect=winedbg says.

--- Comment #2 from Anastasius Focht focht@gmx.net 2011-06-05 13:15:08 CDT --- Hello,
the problem seems to be the default charset/map handling for a symbol font "HP48" the application installs and uses at runtime.

An unhandled failure to select default charmap when the font was initialized leads to a later crash when font->ft_face->charmap is accessed.

The font provides a charmap with encoding -> FT_ENCODING_MS_SYMBOL but this fails to get selected in first place.
lf.lfCharSet -> 1 (DEFAULT_CHARSET) charset -> 0 (ANSI_CHARSET)

Failure of "else" select_charmap() is not handled, leading to a loophole of having no default selected at all.
Maybe if everything fails, the first available charmap (with encoding != 0) in the font's list should be selected as ultimate fallback (face->num_charmaps > 0 -> use face->charmaps[x] if encoding != 0).

That's because winedbg is already (automatically) attached at this point but doesn't get any useful info due to nested exceptions (delphi exception handling braindamage).

--- Comment #3 from butraxz@gmail.com 2013-11-24 12:16:11 CST --- This ticket has not been updated for over 900 days. Development recommends to check the status on your bug every release or two and let to be known if the bug is still present. If not, mark it fixed. If you are no longer able to put effort to this ticket, you can abandon it.
Is this still an issue with 1.7.7 or higher ?
