Bug #: 34990 Summary: Winedbg is unable to set breakpoints when encountering unsupported managed PDB symbol/record types Product: Wine Version: 1.7.7 Platform: x86 OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: dbghelp AssignedTo: wine-bugs@winehq.org ReportedBy: focht@gmx.net Classification: Unclassified
Hello folks,
although Winedbg is not useful for the managed part it might be for getting to a specific failure point.

Unfortunately just doing assert() isn't useful here. It doesn't give any context hence I added a trace message in caller (see 'fixme:dbghelp_msc:codeview_snarf sym->generic.id=xxx').

-> codeview_snarf
When someone works on it ... you might as well clean up all the whitespace/tab mixups here. That file That file definitely needs more love ;-)
I'd expect that winedbg sets the breakpoint regardless of earlier symbol lookup failure.
