Summary: winedbg can't find debuginfo in core libraries when
GNU_HASH section is present in wine-pthread
Product: Wine
Version: CVS
Platform: PC
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: wine-debug
AssignedTo: wine-bugs at winehq.org
ReportedBy: fitzsim at redhat.com
On my x86 Fedora Core 6 machine, winedbg wasn't finding debuginfo for the core
wine libraries.
I tracked down the problem. I compiled wine with the default FC-6 gcc which
passes --hash-style=gnu to the linker by default. is_dt_flag_valid, not
recognizing the DT_GNU_HASH dynamic entry tag, returned 0 when called on that
tag. This resulted in elf_load_file returning before setting
elf_info->dbg_hdr_addr, when loading wine-pthread. elf_info->dbg_hdr_addr
remaining NULL meant that elf_enum_modules_internal returned early, and so
elf_enum_sync_cb wasn't being called for each of the core libraries.
I'm attaching a fix.
