• When capturing a hard crash

Environment

• OS: [e.g. docker image ubuntu:20.04, 64-bit]
• Compiler: [e.g. own arm toolchain]
• CMake version and config: [
  -DCMAKE_TOOLCHAIN_FILE=<own_toolchain>
  -DSENTRY_BUILD_TESTS=OFF
  -DSENTRY_BUILD_EXAMPLES=OFF
  -DSENTRY_TRANSPORT="curl"
  -DSENTRY_BACKEND="breakpad"
  -DSENTRY_EXPORT_SYMBOLS=OFF
  -DCMAKE_BUILD_TYPE=MinSizeRel
  -DSENTRY_LIBRARY_TYPE=SHARED
  -DCURL_INCLUDE_DIR=""
  -DCURL_LIBRARY=""
  ]

Steps To Reproduce

Build curl:
cmake
-DCMAKE_INSTALL_PREFIX=
-DCMAKE_TOOLCHAIN_FILE=
-DCURL_USE_OPENSSL=OFF
-DENABLE_ARES=ON
-DCARES_LIBRARY=
-DCARES_INCLUDE_DIR=
