The user mentioned that certain 16-bit Windows programs crash when run under QEMU's i386-linux-user emulator, specifically showing an error where sigcontext->trapno is -1. They also noted that these programs work fine on a native i386 system. + +The issue seems to be related to how exceptions are handled in WINE. The programs make DOS calls using int 21h, which should trigger an exception that WINE handles by patching the code with its own int21h handling. However, instead of getting the expected trap number, it's -1, causing WINE to treat it as an unhandled error. + +I'm trying to figure out why this is happening. The user isn't sure if it's because of privileged instructions not being handled in 16-bit mode or another illegal instruction case. They provided a QEMU commit reference and mentioned that the behavior was present in version 5.2.0. + +Looking at the possible categories: instruction, syscall, runtime. + +The bug report doesn't mention a specific system call failing but rather an issue with exception handling during DOS calls (int 21h). The problem arises when executing these instructions under QEMU's emulator, leading to incorrect trap numbers in sigcontext. This affects how WINE handles the exceptions. + +So, it seems like the issue is related to how QEMU handles certain instructions, specifically the int instruction used for system calls. Since this leads to an unexpected trap number and causes WINE to mishandle the exception, it's likely a problem with how these specific instructions are being emulated or handled in the emulator. Therefore, the category would be 'instruction'. +</think> + +The bug report describes an issue where QEMU incorrectly handles the int 21h instruction used for DOS calls, leading to incorrect trap numbers and causing WINE to mishandle exceptions.
