This error does not occur on other (admittedly simpler) examples I've tried. Unlike other similar bugs I've found when searching, this does not appear to be an error parsing the command itself, but rather a consequence of the symbols in the executable GDB is run on. test.gdb: set pagination off rbreak . Command run: gdb -x ~/gdb/test.gdb --args asan-firefox-build/mozilla-release/objdir-ff-asan/dist/bin/firefox Last few lines of gdb output: Breakpoint 286 at 0x41f38e: file /mnt/sdb1/home/sandbox/asan-firefox-build/mozilla-release/mfbt/decimal/Decimal.cpp, line 450. WebCore::Decimal WebCore::Decimal::operator/(WebCore::Decimal const&) const; Breakpoint 287 at 0x41f716: file /mnt/sdb1/home/sandbox/asan-firefox-build/mozilla-release/mfbt/decimal/Decimal.cpp, line 320. WebCore::Decimal &WebCore::Decimal::operator/=(WebCore::Decimal const&); /home/sandbox/gdb/test.gdb:2: Error in sourced command file: unmatched quote (gdb) Steps to reproduce: * Compile an ASAN build of Firefox using LLVM * Run it under gdb as above You should see the unmached quote error. I would expect breakpoints to be created without error.
